Short Answer Type Questions

Question 1.

Explain different regions of root with neat labeled diagram.?

Answer:

Root has four regions. They are
a) Root cap
b) Region of rheristematic activity
c) Region of elongation
d) Region of maturation.

a) Root cap :
The tip of the root is covered by a thimble-like structure called the root cap. It gives protection to the root tip as it penetrates into the soil.

b) Region of meristematic activity :
Above the root cap, region of meristematic activity is present. It has meristematic cells. These cells are small, thin walled with dense protoplasm. They divide repeatedly.

c) Region of elongation :
Above the region of meristematic activity, region of elongation is present. The new cells formed grows and elongates. It is responsible for growth of length.

d) Region of maturation :
Behind the region of elongation region of maturation is present. Depending upon the function young cells differentiates into permanent cells. As it matures, it is called region of maturation.

From this region, some of the epidermal cells forms unicellular root hairs. The main function of root hairs is absorption of water from the soil. They are short lived.

Question 2.

Justify the statement: “Underground parts of plants are not always roots”?

Answer:

Normally roots are underground whereas stems are aerial. But in some plants stem grow below the soil. They are called underground stems. They are rhizome corm, stem tuber and bulb.

These underground parts of the plants can be recognised as stem due to presence of nodes, internodes, scale leaves, axillary buds and terminal buds. They can be even identified by their anatomical structures.

For example, stem tubers (Potato), these are underground branches which store food at the tip and becomes tuberous. The tuber is covered by brown coloured layer. It bears many ‘eye’ like structures. These eyes represent the nodes. Each eye has leaf scar and axillary bud. Scar represents the position of scale leaf. Eye help in vegetative propagation.

Question 3.

Explain with examples different types of phyllotaxy?

Answer:

The mode of arrangement of leaves on the stem and branches is called phyllotaxy. It is three types. They are
a) Alternate phyllotaxy :
In this type only one leaf arises at each node in alternate manner.
Eg : Hibiscus, rosa-sinensis (china rose), mustard, sunflower.

b) Opposite phyllotaxy :
In this type, a pair of leaves arise at each node and lie opposite to each other. Eg : Calotropis, Guava.

c) Whorl phyllotaxy :
In this type, more than two leaves arise at a node and form a whorl. Eg : Nerium, Alstonia.

Question 4.

How do leaf modifications help plants?

Answer:

The main function of leaf is photosynthesis and transpiration. In some plants leaves change in their structure to perform new function other than photosynthesis. This is called leaf modification.

1. Tendrils :
In weak stemmed plant, the entire leaf or any part of the leaf is modified into tendrils. They provide mechanical support and help in climbing. Eg: Pea.

2. Spine :
In some plants, leaves are modified into sharp pointed spines. They help in reducing the rate of transpiration in xerophytic plants and also for defence.
Eg: Cacti.

3. Storage leaves :
The fleshy leaves of onion and garlic store food materials.

4. Phyllode :
In some plants such as Australian acacia, the leaves are pinnately compound in which the leaflets are small and short lived. The petioles of these plants expand into green structure performing photosynthesis. These are called phyllode.

5. Insectivorous leaves :
In plants growing in nitrogen deficient soils, leaves are modified to trap insects for their nitrogen requirement.
Eg : Nepenthes (Pitcher plant)
Dionea (Venus fly trap)

6. Vegetative propagation :
In some plants leaves produce buds called epiphyllous buds. They help in vegetative propagation. Eg : Bryophyllum.

Question 5.

Describe any two special types of inflorescences?

Answer:

(Note : Write any two of the following ��
Verticellaster, Cyathium and Hypanthodium are special types of inflorescence.

Verticellaster:

It is a special type of inflorescence found in the family Lamiaceae (Labiatae).
In this type, flowers arise in the axil of leaves arranged opposite to each other at every node.
In the axil of leaf, the flowers are developed initially in dichasial cyme and later in monochasial scorpoid cyme.
Flowers are crowded round the node like a false whorl (verticel). Hence it is called ‘Verticellaster’.
Eg: Leucas and Leonotis.

Cyathium :

This is a single flower like special inflorescence found in family Euphorbiaceae.
The inflorescence is covered by a deep cup like involucre of bracts.
At the centre of this cup there is a single female flower represented by tricarpellary syncarpous ovary.
Surrounding this female flower many male flowers are arranged in monochasial cyme.
Male flowers are represented by single stalked stamen. Male and female flowers are achlamydeous arranged in centrifugal manner. Eg: Euphorbia, Poinsettia.

Hypanthodium :

It is fruit like inflorescence.
In this peduncle is modified into a deep cup like fleshy structure with an apical opening.
The male flowers located near the opening and the female flowers are at the bottom while in between them the sterile female flowers called gall flowers are present.
Pollination in these plants takes place by an insect called Blastophaga which lay its eggs in the gall flowers. After fertilisation the whole inflorescence becomes into a fig fruit.

Question 6.

Describe the arrangement of floral members in relation to their insertion on thalamus.?

Answer:

Depending upon the arrangement of floral members in relation to their insertion on thalamus, flowers are divided into three types. They are
1) Hypogynous :
Thalamus is conical. The gynoecium occupies the highest position. The remaining floral members like calyx, corolla and androecium are at the base of the gynoecium. In this the ovary is called “Superior”.
Ex : Hibiscus, Datura, Mustard, Brinjal etc.

2) Perigynous :
Thalamus is concave or saucer shaped. Gynoecium is situated at the centre. The remaining floral members like calyx, corolla and androecium are arranged along the margin, almost at the same level. In this, the ovary is said to be half inferior or half superior. Ex: Tephrosia, plum, rose, peach etc.

3) Epigynous flower :
In this, thalamus is deep cup like structure, inside it gynoecium is present. The walls of the thalamus and ovary are fused. The remaining floral members are arranged along the margins of the thalamus, i.e. above the level of ovary. So, the ovary is called inferior. Ex : Tridax, guava, cucumber, ray floret of sunflower.

Question 7.

“The flowers of many angiospermic plants which show sepals and petals, differ with respect to the arrangement of sepals and petals in respective whorls’. Explain?

Answer:

The arrangement of sepals and petals in floral bud is known as aestivation. It is of different types.

1) Valvate aestivation :
When sepals or petals in a whorl just touch one another at the margin without overlapping is called valvate aestivation. Eg : Calotropis.

2) Twisted aestivation :
When sepals or petals margin in a whorl overlap one another it is said to be twisted aestivation. Eg: Corolla of hibiscus, cotton, lady’s finger etc.

3) Imbricate aestivation :
If the margins of sepals or petals overlap one another but not in any particular direction is called imbricate aestivation. Eg : Cassia, gulmohur.

4) Vexillary or Papilionaceous aestivation :
In this, there are five petals. The largest petal towards posterior side is called Vexillum or Standard Petal. It overlaps the two lateral petals called Alae or wing petal. These overlap the two smallest petals called keel petals towards anterior side, which are boat shaped. Ex : Bean, Pea.

Question 8.

Describe any four types of placentations found in flowering plants.?

Answer:

The arrangement of ovules within the ovary is known as placentation. They are Marginal placentation: Placenta forms a ridge along the ventral suture of the ovary. Ovules are borne on this ridge forming two rows. Eg: Pea

Axial placentation :
When the placenta is axial and ovules are attached to it in multilocular ovary, it is called axile placentation. Eg: China rose, rose, tomato and lemon.

Parietal placentation :
Ovules born on the inner wall of the ovary or on a parietal part, it is called parietal placentation. Ovary is one chambered but it becomes two chambered due to the formation of the false septum. Eg: Mustard and Argemone. Free central placentation : When the ovules are borne on the central axis without septa, it is known as free central placentation. Eg : Dianthus, primrose.

Basal placentation :
Single ovule is attached to placenta at the base of the ovary. It is called Basal placentation. Eg : Sunflower, marigold.

Question 9.

Describe in brief fleshy fruits by you studied.?

Answer:

In fruits where pericarp becomes fleshy at the time of ripening are called fleshy fruits. Pericarp can be divided into three layers namely outer epicarp, middle mesocarp and inner endocarp. Basing upon the nature of pericarp, fleshy fruits are divided into five types. They are

1) Drupe :
It is one seeded fleshy fruit developed from monocarpellary, superior ovary. The fruit is characterised by stony endocarp. So it is known as Drupe.

In Mango, the outer epicarp is thin, middle mesocarp is fleshy and edible. The inner endocarp is hard stony.
In coconut, the outer epicarp is thin, middle mesocarp is fibrous and inner endocarp is hard stony. The edible part is the endosperm of seed (Copra).

2) Berry :
It is a fleshy fruit having one or more seeds. In this, epicarp is thin. Mesocarp and endocarp are fused to form pulp. Seeds are hard. These fruits develop from bi to multicarpellary syncarpous gynoecium: Eg : Guava, grapes, tomato.

3) Pome :
It is a fleshy fruit developed from inferior ovary of bi or multicarpellary syncarpous gynoecium. It is surrounded by fleshy thalamus. The endocarp is cartilagenous. Eg: Apple.

4) Pepo :
It is developed from tricarpellary syncarpous unilocular inferior ovary. The epicarp is like a rind., the mesocarp is fleshy and the endocarp is smooth. Eg : Cucumber.

5) Hesperidium :
It is developed from multicarpellary syncarpous, multilocular and superior ovary. In this epicarp is leathery with many volatile oil glands. Mesocarp is papery and endocarp has many chambers filled with juicy hairs. Eg : Citrus.

Question 10.

Describe with examples the various dry fruits studied by you?

Answer:

When the fruit wall or pericarp is dry or non-fleshy they are called dry fruits. They are of three types (i) Dry dehiscent (ii) Dry indehiscent (iii) Schizocarpic.
i) Dry dehiscent :
The dry fruit which break open and liberate the seeds are called dry dehiscent fruits. They are of different types.

a) Legume :
The fruits which break dorsiventrally into two halves liberating the seeds are called legumes. It is a characteristic fruit of family fabaceae. Eg : Pea, bean etc.

b) Capsule :
It is a dry fruit which liberates seeds in different ways at maturity. Eg : Cotton, Datura.

ii) Dry indehiscent fruits :
These dry fruits are normally one seeded and never dehisce even at maturity. The seeds are liberated only after the disintegration of the pericarp. They are of following types.

1) Caryopsis :
In this the pericarp and seed coat fuse together. It is a characteristic, . fruit of family poaceae. Ex: Grass, Rice.

2) Nut :
This single seeded dry fruit has a stony pericarp. The pericarp and seed coat remains free. Eg : Cashew.

3) Cypsela :
The single seeded fruit characterized by persistent pappus like calyx. Eg: Tridax.

iii) Schizocarpic fruits :
The fruit which split into one-seeded bits called mericarps are called schizocarpic fruits. Eg: Acacia, Castor.

Long Answer Type Questions

Question 1.

Define root. Mention the types of root systems. Explain how root is modified [Mar. 17 A.P & T.S ; Mar. 15 – A.P & T.S ; Mar. 13]?

Answer:

The part of the plant body present below the soil is called root. It is developed from radicle. There are two types of root sytems.

Tap root system
Fibrous root system

In some plants root is modified to perform new function suitable for the environment. It is called root modification. They are
1) Storage roots :
The roots which store food materials are called storage roots or tuberous roots. In biennial plants, the tap root is modified into storage roots. Depending upon the shape, they are
a) Spindle shape (fusiform) Eg: Radish
b) Cone shape (Conical) Eg: Carrot
c) Top shape (Napiform) Eg: Beetroot
Adventitious roots of sweet potato and fibrous roots in Asparagus store food materials.

2) Prop roots or Pillar roots :
In plants like banyan trees, branches are large and heavy.
From the branches roots arise, they hang in air for sometime and later fixes into the soil.
They are called prop roots or pillars roots.
They act like pillars and gives support.

3) Stilt roots :
In plants like maize and sugarcane roofs arise from the lower nodes of the stem. They are called stilt roots. They give support to plant.

4) Pneumatophores or Respiratory roots :
The Mangrove plants which grow in swampy areas suffer from lack of oxygen as the soils are water lodged. In these plants root comes out of soil and grow vertically upwards. These roots are called respiratory roots or pneumatophores as they take oxygen from air for respiration.

5) Photosynthetic roots :
In Taeniophyllum (epiphyte) the stem and leaves are absent. The roots become green and perform photosynethsis. Such roots are called photosynthetic roots.

6) Velamen roots or Epiphytic roots :
The plants which grow on the branches of big trees for sunlight are
called epiphytes. They have roots which hang freely
in the air. They absorb moisture from the atmosphere. These roots are called velamen roots
or epiphytic roots. Eg : Vanda.

7) Nodular roots :
In members of Fabaceae, the roots show small nodule like structures. Hence it is called nodular roots. In the nodule, Rhizobium bacteria is present. It fixes atmospheric nitrogen into soil. Plant and Rhizobium show symbiotic association.

8) Parasitic roots or Kaustoria :
The plants which depend upon the other plants completely or incompletely for their food and water are called Parasites. They produce parastic roots. They are 1) Complete parasites 2) Partial parasites.
a) Complete parasitic piamts :
These are leafless. So the haustorial root enters into both xylem and phloem to obtain both water and food from the host plant. Ex : Cuscuta, Rafflesia.

b) Partial parasitic plants :
These plants bear leaves. So they can prepare food by photosynthesis. The haustorial roots penetrate only into the xylem tissue of the host to absorb water.

Question 2.

Explain how stem is modified variously to perform different functions. [Mar. 2020, 2019, 14, May 2017 ’14]?

Answer:

When a permanent change occurs in the structure of stems to perform new functions suitable for the environment, it is called ‘stem modification’.

It is of three types. They are
I. Aerial stem modification
II. Sub aerial stem modification
III. Underground stem modification

I. Aerial stem modification :
Modification of aerial stems, vegetative buds and reproductive buds of a plant is called aerial stem modification.
a) Tendril :
Wiry delicate organ useful for climbing are called tendril. Axillary bud modified into tendril in gourds (cucumber, pumpkin, watermelon) or terminal bud in grapevines.

b) Thorn :
A woody pointed structure meant for protection are called thorns. Axillary bud modified into thorn. Eg : Bougainvillea. Terminal bud modified into thorn. Eg : Carissa.

c) Hook :
It is a woody, curved structure which helps in climbing. Ex : Artabotry.

d) Phylloclade :
Leaf like stem performing photosynthesis are called phylloclade. In order to reduce transpiration the leaves are modified into scales, spines etc.
Ex : In Opuntia, fleshy green flattened stem
In Euphorbia, fleshy green cylindrical stem In Casuarina green needle like stem.
Cladode or Cladophyll is a phylloclade of limited growth. Ex : Asparagus.

e) Bulbils :
Buds which show vegetative propagation are called bulbils. Vegetative buds in Dioscorea, Floral buds in Agave.

II. Sub aerial stem modification :
In some weak stemmed plants the stem remains partly aerial and partly underground. These are specialised for vegetative propagation. There are four types.

a) Runner:
Underground stems in some grasses and strawberry and sub-aerial stems in oxalis spread to new nitches and form new plants when older parts die.

b) Stolon :
In some plants slender branches arises grow obliquely downwards, produce roots at the point of contact with soil. These branches are called stolons. Ex : Nerium, Jasmine etc.

c) Suckers :
In plants like banana, pine apple, chrysanthemum part of the stem is in the soil. Underground branches grow obliquely upwards giving rise to leafy shoots. These branches are called suckers.

d) Offset :
In aquatic plants like Pistia and Eichhornia, a lateral branch of one internode length is called offset. At each node it bears a rosette of leaves and balancing roots at the base.

III. Underground stem modification :
Functions of the underground stems are storage of food materials, perennation through unfavourable seasons and vegetative reproduction. So these are called multipurpose stem modification.

a) Rhizome :
It is an underground stem which grows horizontally. It is branched. Ex: Zingiber (ginger).

b) Corm :
It is an underground stem which grows vertically. It is unbranched contractile roots present. Ex : Amorphaphallus (Zaminkand) and colocasia.

c) Stem tuber :
The swollen tip of an underground branch is called stem tuber. It bears many eyes. These eyes represent the nodes. Ex ; Potato.

d) Bulb :
It is a small reduced underground stem. Food is stored in the leaf bases. Ex: Onion.

Question 3.

Explain different types of racemose inflorescences.?

Answer:

Types of racemose inflorescence.
1) Simple Raceme :

2) Compound Raceme :
Peduncle is branched. Each branch resembles a simple raceme. Ex: Mangifera. It is also called Panicle.

3) Simple Corymb :
Peduncle is unbranched and grows indefinitely. On it numerous pedicillate, bracteate flowers are arranged in accropetal manner. The lower flowers have long pedicels and upper flowers have shorter pedicels. Thus all the flowers are brought more or less to the same height. Eg: Cassia.

4) Compound Corymb :
Peduncle is branched and each branch is produced into a simple corymb. Eg: Cauliflower.

5) Simple Umbel :
The peduncle is condensed and unbranched. Many bracteate and pedicellate flowers arise at the tip. At the base of flowers, all the bracts form a whorl called ‘involucre’. Ex: Onion.

6) Compound Umbel :
Peduncle is branched. Each branch produces a simple umbel at its tip. Ex : Carrot.

7) Simple Spike :
Peduncle is unbranched. On it bracteate, sessile flowers are arranged, accropetally. Ex : Achyranthes.

8) Compound Spike :
Peduncle is branched. Each branch is similar to simple spike. Ex: Grass (Poaceae family).

9) Simple Spadix :
Peduncle is unbranched. On it sessile, unisexual and neuter flowers are arranged in acropetal succession. It is protected by modified bract called ‘Spathe’. Ex: Colocasia.

10) Compound Spadix :
Peduncle is branched. Each branch is similar to simple spadix. Ex: Musa, Cocos.

11) Head inflorescence :
Unisexual and bisexual sessile flowers are arranged centripetally on a condensed peduncle. Such an arrangement of flowers is called Head inflorescence. Ex: Tridax, Sunflower (Asteraceae family).

Question 3.

What is meant by homosporous and heterosporous pteridophytes? Give two examples.?

Answer:

The plants which produce only one kind of spores are called homosporous Ex: Psilotum, Lycopodium. The plants which produce two kinds of spores, macro or megaspores and microspores are called heterosporous Ex: Selaginella, Salvinia.

Question 4.

What is heterospory? Briefly comment on its significance. Give two examples.?

Answer:

Producing two types of spores is called heterospory 1) Microspores 2) Megaspores.

Significance :
In heterosporous plants, the megaspores and microspores germinate and give rise to female and male gametophyte respectively. Male gametes are transferred to the egg of female archegonium. The female gametophytes retain on the parent sporophyte for variable period. The development of zygotes into young embryos takes place within the female gametophytes. This event is a precursor to the seed habit. It is considered as an important step in evolution.
Example : Selaginella and salvinia.

Question 5.

Write a note on economic importance of Algae and Bryophytes. [March 2019]?

Answer:

Economic importance of Algae :

About 50% of carbon fixation is done by algae by photosynthesis. Thus by photosynthesis 02 is released into environment.
Algae are primary producers for all aquatic animals in food cycle.
Many species of Porphyra, Laminaria and Sargassum are among the 70 species of marine algae used as food.
Brown algae and Red algae produce large amounts of hydrocolloids (water holding substances) & algin (brown algae) and carrageen (red algae) which are used commercially.
Agar obtained from Gelidium and Gracilaria is used to grow microbes and preparations of ice-creams and jellies.
Iodine is extracted from kelps like Laminaria.
Chlorella and Spirullina are unicellular algae used as food supplements even by space travellers.

Economic importance of bryophytes (mosses) :

Mosses provide food for herbaceous mammals, birds and other animals.
Sphagum provides peat used as fuel, because of its water holding capacity, they are used as packing material for trans-shipment of living material.
Mosses along with lichens are the first organisms to colonise rocks and hence they have great ecological importance.
They decompose rock making it suitable for the growth of higher plants, hence, they play important role in plant succession.
Mosses form dense mats on the soil, they reduce the impact of falling rain and prevent soil erosion.

5) Leaves are isobilateral.	5) Leaves are dorsiventral.
6) Secondary growth is absent.	6) Secondary growth takes place.

Question 7.

Give a brief account of prothallus. [Mar. – 2020]?

Answer:

Haploid spores give rise to gametophytic prothallus in pteridophytes.
Prothallus is small, thin, green and autotrophic thallus like structure.
Prothallus grows in cool, damp, shady places as it requires water for fertilization.
Prothallus bears sex organs. The male sex organs are called antheridia and the female sex organs are called archegonia.
These sex organs are multicellular, jacketed and sessile.
Antheridia produce male gametes called antherozoids. Archegonia has egg cell which is a female gamete.
Antherozoids require water to reach egg.
Zygote develops into embryo within the female gamete. This event is a precursor to the seed habit. It in considered as an important step in evolution.

Question 8.

Long Answer Type Questions

Question 1.

Name three groups of plants that bear archegonia. Briefly describe the life cycle of any one of them.?

Answer:

Bryophytes, pteridophytes and gymnosperms bear archegonia.

Life cycle of a Moss plant:

The gametophyte is a dominant phase.
Moss plant is a haploid gametophore.
It produces gametangia on separate branches of the same plant and hence monoecious.
The club shaped antheridia or antheridial branches produce biflagellate male gametes called “antherozoids”.
The flask shaped archegonia on archegonial branches produce eggs (female gamete) in their venter.
Antherozoids liberated swim in water to reach egg in the venter.
Union of one male gamete (antherozoid) and egg unite results in diploid zygote. This is called fertilization.
Zyeote is the first cell for sporophytic generation. Zygote develops into embryo. Embryo is retained within the archegonium.
It develops into semi parasitic sporophyte consisting of foot, seta and capsule.
The spore mother cells in the spore sac of the capsule undergo meiosis and forms a number of haploid spores of one kind. Hence Funaria is homosporous.
Spore is the first cell for gametophytic generation under favourable conditions, the spore liberated germinates to give rise to filamentous protonema.
The buds arising from the aerial branches of protonema develop into independent gametophores.

Question 2.

Describe the important characteristics of Gymnosperms.?

Answer:

The important characters of Gymnosperms are :

All gymnosperms are perennial, growing as woody trees or bushy shrubs.
Vascular tissues are arranged into vascular bundles.
Flowers are absent, however, microsporophylls and megasporophyll usually aggregate to form distinct cones or strobili called male cones and female cones respectively.
Gymnosperms are heterosporous: Gymnosperms produce two types of spores- Microspores and megaspores. Microspores are produced in Microsporangium. They are called pollen grain. Megaspores are produced in Megasporangia. The megasporangia are integumented and are called ovules.
Ovules are borne on megasporophyll and have three layered integument with an opening called micropyle.
Pollination is indirect.
Fertilization is affected by pollen tube produced by the male gametophyte. It is called siphonogamy.
Endosperm is formed before fertilization. That means female gametophyte is considered as endosperm. It is haploid.
Seeds are naked i.e., without any seed coat.

Question 3.

Give the salient features of pteridophytes?

Answer:

The main plant body of pteridophyte is sporophyte. It is differentiated into true roots, stem and leaves.
Vascular tissues are present. So pteridophytes are commonly called vascular cryptogams.
Roots are adventitious.
Stem is underground rhizome.
The leaves of pteridophytes are small (microphyllous) as in selaginella or large fronds (macrophyllous) as in ferns.
Ferns show circinate vernation and the petioles are covered with brown multicellular hairs called ramenta.
The stele may be protostele or siphonostele or solenostel6.
One of the important characters of pteridophyte is that the sprophyte has become the dominant part of the life cycle while the gametophyte is reduced.
Gametophyte is small and inconspicuous and it is produced from haploid spores known as prothallus.
The asexual generation or the sporophyte may be homosporous (all spores are similar) or heterosporous (two different types of spores) i.e., microspores or megaspores.
Prothallus (gametophytes) are monoecicus or dioecious.
Sex organs are Antheridia and Archegonia.
Male gametes are Antherozoids formed from Antheridia. Antherozoids are uninucleate, spirally coiled, biflagellate or multiflagellate structures.
Union of male gamete and female gamete results in diploid zygote.
Zygote develops into Embryo stage.
True fruit and seeds are not formed at any stage.

Question 4.

Give an account of plant life cycles and alternation of generations?

Answer:

Plant life cycles :
1) Haplontic type of life cycle :
img

The dominant phase is gametophyte. It is photosynthetic free living.
Sporophytic generation is represented by zygote.
Zygote is a resting stage not a free living sporophyte.
Thus the life cycle having only free living gametophyte without free living sporophyte is called Haplontic type of life cycle. Ex :Algae like chlamydomonas, Volvox, Spirogyra etc.

2) Diplontic type of life cycle :
img

The dominant phase is sporophyte. It is photosynthetic independent plant.
Gametophytic generation is represented by gametes.
Thus the life cycle having only independent sporophyte without gametophyte is called Diplontic type of life cycle.
The life cycle having only independent sporophyte with few celled or many celled staged gametophyte is called diplo-haplontic type of life cycle.
Ex: Pteridophytes and seed-bearing plants.

3) Haplo-diplontic type of life cycle :

The dominant phase is gametophytic generation. It is independent.
Sporophytic generation is photosynthetic dependent on gametophytic generation.
The life cycle having both dominant gametophytic generation and dependent sporophytic generation is called Haplo-diplontic type.

Alternation of generations:

In the life cycle of an organism two phases are present. They are Gametophytic phase and Sporophytic phase.
Haploid spore is the first cell for gametophytic generation.
Haploid spore divides mitotically and forms haploid gametophyte.
Gametophyte shows sexual reproduction. It forms male and female gametes.
The fusion of male and female gametes results in diploid zygote.
Diploid zygote is the first cell for sporophytic generation.
Diploid zygote divides mitotically and forms diploid sporophyte.
Diploid sporophyte shows asexual reproduction. It undergoes meiosis and forms haploid spores.

Thus during the life cycle of plants gamete producing haploid gametophyte alternates with spore producing diploid sporophyte. This is known as alternation of generation.

Question 5.

Both Gymnosperms and Angiosperms bear seeds, then why are they classified separately?

Answer:

Even though both Gymnosperms and Angiosperms bear seeds, they are classified separately because of nature of seeds.

In Gymnopserms:

The plant bears ovules which are not covered by any ovary wall. They remain exposed.
Pollination is direct.
Seeds formed are not covered by seed-coat. They are naked seeded plants.
Female gametophyte is considered as Endosperm as it is nutritive in function.
Endosperm is formed before fertilisation.
It is haploid.
Poly embryonic condition is present.

In Angiosperms:

The plant bears ovules which are present inside the ovary. They are not exposed.
Pollination is indirect.
Seeds formed are covered by seed – coat. They are closed seeded plants.
Endosperm is formed after double fertilisation and triple fusion.
Endosperm is triploid.
Single embryo is present.

Intext Question Answers

Question 1.

How far does SelagineJIa, one of the few living members of Lycopodiales (Pteridophytes) fall short of seed habit.?

Answer:

Selaginella is heterosporous. It produces two kinds of spores. They are macrospores and microspores. Macrospores germinate and give rise to female gametophyte whereas Microspores give rise to male gametophyte. Fusion of male gamete with the egg present in the archegonium results in the formation of Zygote. The development of zygotes into young embryos takes place with the female gametophyte. This is the precusor to the seed habit.

Question 2.

Each plant or group of plants has some phylogenetic significance in the relation of evolution. Cycas, one of few living members of Gymnosperms is called as the “relic of past”. Can you establish a phylogenetic relationship of Cycas with any other group of plants that justifies the above statement?

Answer:

Cycas, one of Gymnosperms shows close resemblance with fern (pteridophyte) on one hand and angiosperms on the other hand. Thus occupying a position intermediate between the two.

Certain primitive characters in cycas are similar to ferns. They are

Stem when young is underground and subterranean.
Leaf bases are persistent on the stem.
Young leaves show circinate vernation.
The sporophylls are leaf-like.
Ramenta are present.
Xylem consists of tracheids only and there are no vessels.
Phloem lacks companion cells.
Microsporangia occur in sori on the abaxial side of microsporophyll.
Archegonia are still retained in the female gametophyte.
Sperms are multiciliate.

Question 3.

The male and female reproductive organs of several pteridophytes and Gymnosperms are comparable to floral structures of angiosperms. Make an attempt to compare the various reproductive parts of Pteridophytes and Gymnosperms with reproductive structures of Angiosperms.?

Answer:

Reproductive structures of Pteridophytes are strobili or cone.	Reproductive structures of Gymnosperms are strobili or cone.	Reproductive structures of Angiosperms are flowers.
Cone is not differentiated as male cone and female cone.	Male cone and female cone are present.	Flowers may be unisexual as male flowers and female flowers. (or) Flowers may be bisexual.
Mostly homosporous Sporophylls bear sporangia which produce spores. Some are heterosporous Microsporophyll bearing Microsporangia produce Microspores. Macrosporophyll-bearing Macrosporangia produce Macrospores.	The male cone bearing Microsporophyll and Microsporangia are called microsporangiate or male strobili. (This is similar to male flower) They produce Microspores.The female cone bearing Megasporophyll and Megasporophyll with ovule or integumented mega-sporangia are called megasporangiate or female strobili (This is similar to female flower)	The male sex organs are called stamen or Microsprophyll.Anther represents microsporangium.Pollengrains represent microspores.Female sex organ carpels represent Megasporophyll. Carpel is with ovule or integumented Megasporangia.

Question 4.

The plant body in higher plants is well differentiated and well developed. Roots are organs used for the purpose of absorption. What are the equivalent of roots in the less developed lower plants?

Answer:

Rhizoids. They are unicellular or multicellular hair-like structures that penetrate the moist soil and absorb the water for the plants.

Answer:

We prove this result by using mathematical induction suppose n = 1 then
A’ = $\left[\begin{array}{ccc} \mathrm{a}_1 & 0 & 0 \\ 0 & \mathrm{a}_2 & 0 \\ 0 & 0 & \mathrm{a}_3 \end{array}\right]$ = A
The result is true for n = 1.
Suppose the result for n = k then

The result is true for n = k + 1.
So by the principle of mathematical induc-tion the statement is true ∀ n ∈ N.

Answer:

Question 5.
A trust fund has to invest Rs. 30,000 in two different types of bonds. The first bond pays 5% interest per year, and the second bond pays 7% interest per year. Using matrix multiplication determine how to divide Rs. 30,000 among the two types of bonds, if the trust fund must obtain an annual total interest of (a) Rs. 1800 and (b) Rs. 2,000.
Answer:
Let the first bond be ‘x’, then the second bond will be 30,000 – x.
Rate of interest are 5% and 7% means 0.05 and 0.07.
a) [x 30,000 – x] $\left[\begin{array}{l} 0.05 \\ 0.07 \end{array}\right]$ = [1800]
⇒ 0.05x + 0.07 (30,000 – x) = 1800
⇒ – 0.02x + 0.07 (30,000) = 1800
⇒ – 0.02x + 2100 = 1800
⇒ – 0.02x = – 300
⇒ x = $\frac{300}{0.02}$ = 300 × $\frac{100}{2}$ = 15, 000
First bond = 15, 000
Second bond = 30,000 – x
= 30,000 – 15,000 = 15,000

(b) [x 30,000 – x] $\left[\begin{array}{l} 0.05 \\ 0.07 \end{array}\right]$ = [2000]
⇒ 0.05x + 0.07 (30,000 – x) = 2000
⇒ – 0.02x + 0.07 (30,000) = 2000
⇒ – 0.02x + 2100 = 2000
⇒ x = $\frac{100}{0.02}$ = 5, 000
∴ Second bond = 30,000 – x
= 30,000 – 5,000
= 25,000
