Class 10 Concise ICSE Biology Selina Solutions Ch-5

Que-1:  Given below is an example of a certain structure and its special functional activity

chloroplasts and ….photosynthesis…

In a similar way, write the functional activity against each of the following:

(a) Hydathodes and ……………

(b) Leaf spines and ……………

(c) Lenticels and ……………

(d) Xylem and …………..

Sol:

(a) Hydathodes and guttation.

(b) Leaf spines and protection and reduced transpiration.

(c) Lenticels and transpiration.

(d) Xylem and conduction of water and mineral salts.

Que-2: State whether the following statements are True (T) or False (F)? Rewrite the false statements in the correct form

(i) Most transpiration occurs at midnight.

(ii) Transpiration creates a pull for the upward movement of the sap.

(iii) Wind velocity has an effect on transpiration.

(iv) Atmospheric humidity promotes transpiration from a green plant.

(v) Transpiration helps to cool the body of the plant.

Sol:

(i) False
Corrected statement — Most transpiration occurs at mid-day.

(ii) True

(iii) True

(iv) False
Corrected statement — Atmospheric humidity reduces transpiration from a green plant.

(v) True

Que-3: Match the terms given in column A with column B:

Column A	Column B
(a) Hydathodes	(i) Photosynthesis
(b) Stomata	(ii) Respiration
(c) Cuticle	(iii) Regulates opening and closing of stomata
(d) Lenticels	(iv) Reduces loss of water
(e) Guard cells	(v) Guttation

Sol:

Column A	Column B
(a) Hydathodes	(v) Guttation
(b) Stomata	(i) Photosynthesis
(c) Cuticle	(iv) Reduces loss of water
(d) Lenticels	(ii) Respiration
(e) Guard cells	(iii) Regulates opening and closing of stomata

Que-4: Name these

(a) Three kinds of transpiration.

(b) Three external factors which increase the rate of transpiration.

(c) Three intrinsic features which reduce the rate of transpiration.

(d) Three extrinsic factors which decrease the rate of transpiration.

(e) Four kinds of potometers on the basis of the name of scientists who discovered them.

Sol:

(a) Three kinds of transpiration:

1. Stomatal transpiration.
2. Lenticular transpiration.
3. Cuticular transpiration.

(b) Three external factors which increase the rate of transpiration:

1. Increase in intensity of Sunlight.
2. Low humidity.
3. Increase in velocity of wind.

(c) Three intrinsic features which reduce the rate of transpiration:

1. Sunken stomata.
2. Narrow leaves.
3. Thick cuticles.

(d) Three extrinsic factors which decrease the rate of transpiration:

1. Increase in humidity.
2. Increase in carbon dioxide level in atmosphere.
3. Increase in temperature.

(e) Four potometers named after their discoverers :

1. Farmers’s potometer
2. Ganong’s potometer
3. Darwin’s potometer
4. Garreau’s potometer
