Question:
Will the ascent of sap be possible without the cohesion and adhesion of the water molecules? Explain.
Solution:
No. it is not possible because these are responsible for the same. The continuous water column in the xylem vessels for the sap ascent is maintained by the adhesive and the cohesive forces of water. Absence of which would have led to cavitation of xylem vessels or breakage of the water column or the sap movement upwards.
