Will the ascent of sap be possible without the cohesion and adhesion of the water molecules ? Explain.

Explanation

No, the ascent of sap is not possible without the cohesive and adhesive properties of water as they play an important role in trensport of water because of the following reasons
(i) Cohesion forces hold together the water molecule in the conducting channels, so vacuum is not created.
(ii) Adhesive force between the water molecule and cellulose of cell wall make a thin film of water along the channels so, this film can be pulled up by transpiration pull drawing more and more water upwards in the conducting channels from the root.
