Capillary action is one of the forces that aids water's upward movement in plants. The narrower the diameter of the tube, the farther the water column will rise. Capillary action is a result of water molecules:
A. producing sufficient surface tension to overcome the pull of gravity.
B. having a strong cohesive force and attaching to the surrounding vessel walls.
C. storing heat and thus moving faster because of heat of vaporization.
D. having an adhesive force, which allows them to attach to the vessel walls.
E. being associated with hydrophobic molecules, which can result in upward movement.
