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

Solution:

No, because these are the ones who are in charge of the same. The adhesive and cohesive properties of water maintain a continuous water column in the xylem vessels for sap ascent. Absence of which would have resulted in xylem vessel cavitation, water column fracture, or sap migration upwards.
