Transpiration pull and water cohesion theory

Vedclass · Answer

(D) The movement of water against gravity in plants is primarily explained by the Cohesion-Tension-Transpiration Pull theory. $1$. Cohesion: The strong attraction between water molecules due to hydrogen bonding creates a continuous water column in the xylem. $2$. Adhesion: The attraction between water molecules and the xylem vessel walls prevents the column from breaking. $3$. Transpiration Pull: As water evaporates from the stomata in leaves,it creates a negative pressure (tension) that pulls the entire water column upward from the roots. Therefore,both transpiration pull and the cohesive properties of water are essential for this process.
