|
Why does temperature increase the rate of transpiration?
|
|
Higher temperature allows gas molecules to move faster
|
|
|
Higher temperature allows water to evaporate faster in the leaf
|
|
|
Higher temperature allows the stomata to open wider.
|
|
|
Higher temperature allows the enzymes to function better.

Explanation:
Detailed explanation-1: -As the temperature increases, the water molecules gain more energy. This means they move around more and therefore they evaporate and diffuse out of the leaf faster. This is why the rate of transpiration increases as the temperature increases.
Detailed explanation-2: -Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.
Detailed explanation-3: -Solar radiation, the temoerature of the air surrounding the leaf, relative humidity, wind velocity, and the availability of soil moisture all have a direct influence on transpiration rates.
