snow_lady [41]

Answer:

enable capillarity

Explanation:

It is well known that water tends to adhere to the walls of the vessel in which it is contained. This is due to the force of adhesion which is defined as the force of attraction between unlike molecules. Cohesion is defined as the force of attraction between like molecules. In the case of a plant, cohesion of water molecules in the xylem vessels prevents the water column from breaking. The forces of adhesion, surface tension and cohesion are the basis of capillarity,that is, the rise of liquids in capillary tubes.
