Water goes up through xylem vessels in tall trees. The process in plants and properties of water that help in upward movement are :
Respiration and cohesion
Transpiration pull, cohesion and adhesion
Root pressure, cohesion and adhesion
Transpiration and adhesion
Answer is Right!
Answer is Wrong!

UPSC CDS-2 – 2023
Transpiration pull is the force generated by the evaporation of water from the leaves (transpiration). This pull creates tension in the water column within the xylem. Cohesion is the property of water molecules to stick together due to hydrogen bonding, maintaining an unbroken water column. Adhesion is the property of water molecules to stick to the hydrophilic walls of the xylem vessels, preventing the water column from breaking and helping it climb upwards against gravity.
