Capillarity refers to the mechanism through which the water moves extremely inside the thin tubes aided through the attraction between the capillary wall and the water molecules. The phenomenon of the capillarity is possible since the water is a polar molecule and forms the intermolecular hydrogen bonds. Thus, there exists the electrical attraction (adhesion force) between capillary wall and water molecules that then pull each other (cohesion force) as they are bound. Not just the water but other liquids may move inside the capillaries through the capillarity. Capillarity is not too relevant for transport of the water in the plants. It contributes only to the few centimetres of the ascension.
