Vedclass · Answer

(B) Transpiration creates a negative pressure potential (transpiration pull) in the xylem vessels,which is essential for the upward movement of water from the roots to the leaves. Therefore,transpiration directly facilitates the conduction of water through the plant. While it is linked to stomatal function,the primary physiological process it drives is the ascent of sap.
