The plant cells away from the sun grow faster than those on the sunny side causing the plant stem to bend toward the sun.
due to capillary action
capillary rise
capillary action
Capillary rise in plants helps in the transportation of water from roots to leaves. In insects, capillary action assists in the movement of liquids through small channels like tracheae and tracheoles. In sea sponges, capillary action helps in filtering and absorbing nutrients from water.
The 'capillary effect'. See the link.
Examples of capillarity include the ability of water to rise in a narrow glass tube (capillary action), the spread of ink on paper through capillary action, and the movement of water through the roots and stems of plants.
deduce an expression for height of a liquid in capillary tube. also write practical applications of capillary action.
That is capillary attraction.

The property of water that gives rise to capillary action is adhesion, which is the attraction between water molecules and the molecules of the material making up the capillary tube. This leads to water being pulled up the tube, against the force of gravity, due to the cohesive forces between water molecules.
Cohesion is the attraction between molecules of the same substance. Capillary action is the tendency of water to rise in a thin tube. As one molecule of water is pulled up the plant's capillary, it pulls the other molecules up because of cohesion.
