Question

Increase in temperature and velocity of the wind cause an increase in transpiration initially but later it slows down, because

• A. Of closure of stomata
• B. Water is not made available
• C. The air around the plant becomes humid
• D. Of mechanical disturbance

Answer 1

The correct option is A Of closure of stomata

Transpiration is physiological evaporation. At high wind velocity and high temperature, the rate of transpiration is increased but subsequently with very high temperature stomata is closed due to loss of turgor in guard cells.
