Question

- The loss of water from the leaves of the plant is called transpiration . How this process is advantageous for the plants *


a) It helps in downward movement of the water

b) It helps the plant to maintain temperature in hot sunny days

c) It acts as a driving force for distribution of food in plants body

d) It helps maintain a constant level of water in the soil around the plant

​

Answer 1

b) It helps the plant to maintain temperature in hot sunny days

Answer 2

Answer:

The loss of water from the leaves of the plant is called transpiration. Option b is correct that it helps to maintain the temperature in hot sunny days

Explanation:

• The plants absorb water through roots and evaporate water through stomata in the leaves is called transpiration.  

• During summer, the plant absorbs excess energy, and the temperature of the leaf increases.

• Due to a rise in temperature, the excess amount of water is removed in the form of water vapor due to transpiration process and automatically it lowers the temperature of the plant. So, option b is correct.
• Option a is incorrect. The transpiration helps in upward movement of the water.
• Option C is incorrect because transpiration acts a driving force to remove the water from the plants.
• Option d is incorrect. The transpiration maintains the turgidity of the cells. Because excess amount of water is removed to prevent the decay of the plants.
