cohesion/adhesion

a hydrogen bond

Detailed explanation-1: -Adhesion happens because the water prefers to stick to the tube, causing capillary action.
Detailed explanation-2: -In the xylem vessels, water molecules are strongly attracted to each other and exhibit a “stickiness” called cohesion that is due to the formation of hydrogen bonds between different water molecules. The “stickiness” between water molecules and the xylem vessel walls is called adhesion.
Detailed explanation-3: -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-4: -Answer and Explanation: Three properties of a water molecule enable it to move from the root system to the leaves of the plant. They are cohesion, adhesion, and high surface tension.
