Transpiration Diagram A Level. Evapotranspiration et is the sum of water evaporation and transpiration from a surface area to the atmosphere evaporation accounts for the movement of water to the air from sources such as the soil canopy interception and water bodies transpiration accounts for the movement of water within a plant and the subsequent exit of water as vapor through stomata in its leaves in vascular plants. Guard cells control the movement of water vapour in and out of the stomata by changing shape to increase or reduce the size of the stomatal opening.
Transpiration is very important for maintaining moisture conditions in the environment. 10 of atmospheric water originates from transpiration. Evapotranspiration et is the sum of water evaporation and transpiration from a surface area to the atmosphere evaporation accounts for the movement of water to the air from sources such as the soil canopy interception and water bodies transpiration accounts for the movement of water within a plant and the subsequent exit of water as vapor through stomata in its leaves in vascular plants.
Wind speed availability of water to the plant and air temperature all affect the rate of transpiration at any one time.
Guard cells control the movement of water vapour in and out of the stomata by changing shape to increase or reduce the size of the stomatal opening. Out of the leaf. Transpiration is the evaporation of water from plants. Out of the leaf.
