Cohesion tension hypothesis Definition:
According to their cohesion-tension hypothesis, transpiration provides the pull for the ascent of xylem sap, and the cohesion of water molecules transmits.

Cohesion tension hypothesis Notes:
Cohesion tension hypothesis explains the ascent of water from roots to leaves in a plant as due to a combination of upward pull created by transpiration losses producing a tension on the xylem vessels and cohesion of water molecules to each other, aided by the adhesion of water molecules to the sides of the narrow vessels.
