Solution

The correct option is D

adhesion force


In plants, transportation of water and minerals take place through the xylem. The method used in the upward movement of water through the xylem is determined by the cohesion-tension theory. The cohesive force, i.e., the attractive force between water molecules, and the adhesive force, force between water molecules and the xylem walls, are responsible for a continous flow of water upwards.
