Transpiration pull and Transpiration.
Transpiration pull: In higher plants water is transported through xylem. This movement is accomplished by 'pulling' of water to the leaves of the plant. This is referred to as cohesion-tension-transpiration pull model of water transport. This takes place in the higher plants . Transpiration Less than 1 percent of water is utilized in the process of photosynthesis. Water is lost from the plants through stomata in the form of vapour on the surface of leaves. This process of removing water through stomata of leaves in the form of vapour is called as Transpiration.
