Biology:

Suggested answers:

Ans.(a)

Upper epidermis

Palisade fayer

layer

(a) The cells of the palisade

layer contain most chloro- plasts.

; (ii) chlorophyll present in the chloroplasts is invariably and specifically associat- ed with the process of photosynthesis in a green plant. The function of chlorophyll includes: (1) it absorbs certain wave rengths of radiant energy. and either converts this energy into other wave lengths which are used in photosynthesis, or trans- fers the absorbed energy directly to compounds. involved in the reaction; (2) it acts in the capacit ty of a catalyst at some stages of the photosynthet -ic process •

(iii) If A (the waxy substance)

was absent in the leaf, and the leaf may be affect

-ed by the following: (1) Much water loses from

the leaf to the atmos- a phere by transpiration (2)the leaf tissues may suffer the attack by micro-organisms.

of B.

(iv) Three functions (

(Vascular tissue in a

vein) are:

(1) to provide a mechani-

.cal support for the

leaf tissues..

(2) to carry water and

soluble minerals from the shoot to other fparts of the leaf. (3) to carry the manufact-

ured food away from the leaf to the shoot..

(v) Two gases that Pass out

of C (stomatal pore) dur- ing the day are oxygen and water vapour.

(b)

hydroxide

(i) Since the experimental

apparatus aims to prove that carbon dioxide is essential for photosynth- esis, so that the follow- ing test should be done to complete the experiment The

processes of the test are described as follows: (1) Kill the living

tissues of the leaf by boiling it in water:

(2) Extract the chlorophy

-11 from the leaf by boiling it gently: in alcohol.

(3) When the, leaf has

turned cream colour, remove the leaf and rinse it in water. (4) Spread the leaf out

in a watch glass and a few drops of iodine solution is added to the leaf surface." (ii) The colour of the leaf remains unchanged i.e. no starch is formed in the leaf which has been deprived of carbon dioxi- de supply. (iii) To ensure that carbon

dioxide is essential for photosynthesis.

(iv) In the experimental

apparatus, the leaf is deprived of carbon dioxide supply, while the Leaf placed in the control. apparatus receives a constant supply of carbon dioxide because potassium hydroxide has been remov- ed from it,

5. Ans(a)(i) The problems of

the parasitic mode of life may be considered as the following respects:-

(1) All parasites may not live independently by themselves. They are parasitic on other organisms.

(2) All parasites have to

absorb 1ood in solut-

ion from the host

organisms.

(3) All parasites suffer

unfavourable condition -s during their life.

(4) Numerous gametes must be produced. This compensates for the great loss during. reproduction.

Dodder is adapted to its parasitic mode of life by the following:

(1) The stem is thread-like

and twins round the stem. of the host, so that it. is easily supported by the host.

(2) Germination of seeds es place in the late spring when the host: plant has already deve→ Joped.....

(3) The intervals haustoria.

penetrate the vascular tissues of the host and enable it to obtain:: supplies of food and. water.

These

(4) Numerous pink flowers

resulting the production of numerous seeds.. compensate for the great: loss during germination. (5) The seeds are relatively large and their food... content" is thus appreci– able. This is important to ensure the survival of the seedling during the: free living stage..

Tapeworm is also adapted to its parasitic mode of life. by the following:- (1) A thick cuticle protects: its body from the digest- ion by the digestive juice of the host.

(2) The presence o of hooks and

suckers on the scolex: serve as organs for attachment and absorptior: (3) It breathes anaerobically because there is an absen -ce of free oxygen in the host's alimentary canal. (4) Each body proglottis of.

the worm is a hermaphrod- ite which enables the: worm to. proceed self-

fe

(5) An

reproductive system produces numerous eggs... This compensates for the great loss durine. the completion of its life cycle.

(ii) Methods of control of the

tapeworm:-

(1) Cooking is a safeguard.

to prevent the intake of this parasite because bladder worms are killed by heat.

(2) Human feeces should be

strictly disposed of in; order to prevent the intake of the fertilized eggs by the secondary host e.g. pig.

(3) The government authority.

should inspect the sale of "measly" pork or beef not to be sold for human food.. (4)Pigs should be kept.

under sanitary conditior

(b)(i) A terrestrial insect has small openings, called spiracles, on the side of the segment of the body. These lead to a system of branched.. tracheae-spreading

throughout the internal tissues of the body.. Air is pumped in and out of the tracheae by the muscular contractions and expansions of the abdomen. In this way, oxygen is taken from the surroundings into the body of the insect. (ii) An amphibian in the

adult stage e.g. frog, breathes in oxygen from the surroundings by the following ways:-

(1) Skin respiration

Its skin is smooth, moist and well supplied with blood capillaries. Oxygen from atmospheric air or water dissolves. in the film of moisture over the skin, diffuses through the skin and through the thin-walled capillaries into the blood.

(2) Lung respiration

In which air is forced into the lungs by raising the mouth- floor. This type af breathing is practised only when the animai lives on land or swims. at the surface, the nostrils having valves to prevent entry of water and control the flow of air movement into lungs.

(3) Mouth respiration

The moist lining of the large mouth supplied with blood capillaries also serves as a respiro atory surface. It is. in constant use, except when:submerged, but the movements of the mouth- floor can be used to exchange the air in it. (iii) Water is constantly

entering the mouth of

a bony fish, and passing. out through openings on both sides of the head. The gills have numerous thin-walled gill fila-

·ments which are well supplied with blood capillaries. As the water passes over the

gill filaments, oxygen. diffuses through the thin membrane into the blood.
