Intro to Botany
Capillary action is the process by which water moves upward through narrow spaces, such as soil or plant xylem, against the force of gravity. This phenomenon occurs due to the combination of adhesion (the attraction between water molecules and other surfaces) and cohesion (the attraction between water molecules themselves). This movement is crucial for plants as it enables the transport of water and nutrients from the roots to the leaves, thereby supporting vital biological processes.
