Q. 24.8( 5 Votes )

Which one of the following will not directly affect transpiration?
A. temperature

B. light

C. wind speed

D. chlorophyll content of leaves

Answer :

Increased light intensity increases the rate of photosynthesis hence water is drawn into the leaves where photosynthesis takes place and this opening of stomata also leads to increased rate of transpiration.

When wind speed is more, then more molecules are carried away by the windi.e when air outside the stomata is less humid. Increased temperature increases the energy of the water molecules and hence leads to increased rates of transpiration in form of water vapour.
