Cohesion

Vedclass · Answer

(B) The ascent of sap in plants is primarily driven by the cohesion-tension theory. $1$. Cohesion refers to the mutual attraction between water molecules due to hydrogen bonding. $2$. Adhesion refers to the attraction of water molecules to the polar surfaces of the xylem vessel walls. $3$. Surface tension is the property where water molecules are more attracted to each other than to air. $4$. Among these,the high cohesive force (Cohesion) allows water to form a continuous column in the xylem,which can withstand the tension created by transpiration pull. Therefore,cohesion is the most critical property for the ascent of sap.
