Biology for IGCSE & O level - Transport In Plants (Section 2 - No. 1)
What drives the movement of water up the xylem in a plant?
Cohesion of water molecules
Adhesion of water molecules to the xylem walls
Root pressure
Active transport
Explanation
Cohesion, adhesion, and root pressure all contribute to the movement of water in the xylem, pulling water up the plant. Active transport is not directly involved.
