Cohesion and adhesion are crucial for the movement of water and nutrients in trees. Cohesion allows water molecules to stick together, forming a continuous column that can be pulled upward through the xylem during transpiration. Adhesion helps water molecules adhere to the walls of the xylem vessels, preventing them from breaking apart under tension. Together, these properties facilitate the upward movement of water from the roots to the leaves, enabling nutrient transport throughout the tree.
