Xylem: Upward Water Movement in Plants

The video explains how water is transported in plants through xylem, which consists of tracheids and vessel elements. Water enters through root hairs and moves upward due to root pressure, adhesion, cohesion, and capillary action. Transpiration, driven by evaporation from stomata, creates a transpiration pull that is crucial for water movement, especially during sunny days.

How does root pressure assist in the upward movement of water in plants?

Explain the process of capillary action in relation to xylem.
