Explanation:
Detailed explanation-1: -Capillary action draws water up within the xylem. Cohesion-tension pulls water up the xylem.
Detailed explanation-2: -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.
Detailed explanation-3: -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.
