|
|
Air around the leaf with high humidity.
|
|
|
Air molecules around the leaf with less kinetic energy.
|
|
|
An absence of light falling on the leaf.
|
|
|
Water molecules in the leaf with more kinetic energy.
|
Detailed explanation-1: -Temperature-increasing temperature increases the rate of transpiration because more heat energy means that the water molecules have more kinetic energy and will diffuse faster out of the stomata. This increases the water potential gradient between the inside and outside of the leaf.
Detailed explanation-2: -Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (a mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.
Detailed explanation-3: -The light intensity, temperature, humidity, wind and water supply will all affect the transpiration rate.
