Capillary action, or capillarity, is a phenomenon where liquid rises in a narrow space such as a thin tube, or in porous materials. This effect can cause liquids to flow against the force of gravity. This behaviour of water allows plants to take in water through the roots and up the stems to be distributed throughout the plant.
