Here's how it works:
* Cohesion: Water molecules are attracted to each other (cohesion). This strong attraction creates a continuous column of water within the plant's vascular system (xylem).
* Adhesion: Water molecules are also attracted to the walls of the xylem vessels (adhesion). This creates a thin film of water along the inside of the xylem.
* Surface tension: The cohesive forces between water molecules at the surface create a tension that pulls the water column upwards.
Together, these forces overcome the force of gravity and allow water to travel from the roots to the leaves of plants, even against significant heights.
