Verified step by step guidance1
Understand that water movement in plants involves the process of capillary action, which is crucial for transporting water from roots to leaves.
Recognize that capillary action is the result of two key properties of water: adhesion and cohesion.
Adhesion refers to the attraction between water molecules and the walls of the plant's xylem vessels, allowing water to climb upward.
Cohesion refers to the attraction between water molecules themselves, which helps maintain a continuous column of water as it moves through the plant.
Combine these concepts to see how capillary action, driven by adhesion and cohesion, enables water to move against gravity from the roots to the leaves of a tree.
