Answer:
Hey <3
Explanation:
Capillary action pulls water into the root of a tree while the forces of cohesion and adhesion continually move the water up the tall tree.
Water is a polar molecule. Strong hydrogen bonds hold the water molecules together. This is a kind of dipole - dipole interaction and it accounts for the cohesive forces in water.
The forces of adhesion bind water to other surfaces. In the case of plants, the adhesive forces facilitates the interaction of water with the xylem cells.
Water enters into the roots of plants by capillary action. Capillary action alone is insufficient to move the water up the tree.
Hence, the forces of adhesion and cohesion, acting together can help water molecules to move up the top of a tall tree.
