Transpiration

Vedclass · Answer

(B) The unidirectional movement of water from roots to the leaves against gravity in plants is primarily explained by the $Transpiration$ $Pull$ theory.Transpiration is the process of loss of water in the form of water vapor from the aerial parts of the plant.This loss of water creates a negative pressure (tension) in the xylem vessels, which pulls the water column upwards from the roots to the top of the plant.Therefore, transpiration is the driving force for the ascent of sap.
