The movement of water is through transpiration puli'



The movement of water is through transpiration puli’. Discuss if this statement is 100% true. Give explanation for your answer.


The statement mentioned above is partially true. Transpiration pull is the major factor, which facilitates movement of water in xylem. But there are other factors that also play a major role. Cohesion-adhesion and surface tension gives high capillarity to water molecules, which enables it to reach a certain height in plant’s xylem. Transpiration pull has an augmentative effect on the surface tension push. So in totality it is cohesion-adhesion-surface tension and transpiration pull, which does the whole function of transporting water to greater heights in plants.
