Water goes up through xylem vessels in tall trees. The process in plants and properties of water that help in upward movement are :

  1. A. Respiration and cohesion
  2. B. Transpiration pull, cohesion and adhesion
  3. C. Root pressure, cohesion and adhesion
  4. D. Transpiration and adhesion

Correct Answer: B. Transpiration pull, cohesion and adhesion

Explanation

The ascent of sap in tall trees is primarily driven by transpiration pull (creating a negative pressure), supported by the cohesion between water molecules and their adhesion to the xylem walls.
