Vedclass · Answer

(B) The cohesion-tension theory,also known as the transpiration pull theory,states that the ascent of sap is a passive process. It relies on the physical properties of water (cohesion,adhesion,and surface tension) and the transpiration pull generated by the leaves. The xylem vessels are dead cells at maturity and do not require metabolic energy for the transport of water. Therefore,the statement that living cells of roots play an active role in the ascent of sap is incorrect,as the process is primarily driven by transpiration and physical forces.
