Cohesion helps plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. This transport occurs even in large trees and against gravity. Transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.
