The property of water that allows water to move up a thin tube (or the stem of a plant) by itself

Detailed explanation-1: -A wet fluid displays such type of capillary action that is further caused due to the forces of cohesion and surface tension acting together. Capillary action is the resultant of intermolecular attraction between the molecules of water and the adhesive force in between the walls of the capillary and the liquid.
Detailed explanation-2: -Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances).
Detailed explanation-3: -Capillary action occurs because water molecules bond each other strongly due to forces of cohesion and adhesion where water molecules are attracted and stick to other substances such as glass or paper. Adhesion of water to the surface of a material will cause an upward force on the liquid.
Detailed explanation-4: -Plants use capillary action to bring water up the roots and stems to the rest of the plant. The molecules of the water (the liquid) are attracted to the molecules of the inside of the stem (the solid). This attraction is used to help force the water up from the ground and disperse it throughout the plant.
Detailed explanation-5: -Adhesion happens because the water prefers to stick to the tube, causing capillary action.
