Question

rate of transpiration is directly proportional to the surface area of the leaves true or false​

Answer 1

Answer:

The rate of transpiration is roughly inversely proportional to atmospheric humidity. When there is diffusion of water vapors through stomata, it is in accordance with the law of simple diffusion, meaning, the rate of transpiration is greatly reduced when the atmosphere is very humid. As the air becomes dry, the rate of transpiration also increases proportionately.

The rate of transpiration is roughly proportional to the intensity of light.

With the increase in atmospheric temperature, the rate of transpiration also increases.

The availability of soil water is proportional to the rate of transpiration. If there is little water available, the resulting tendency for dehydration of the leaf causes stomatal closure and a consequent fall in transpiration
