🌿 What is Transpiration Pull? Transpiration pull is a vital mechanism in plants that facilitates the upward movement of water from the roots to the leaves. This process is driven by the evaporation of water from the leaf surfaces, primarily through structures called stomata . 🧬 How Does Transpiration Pull Work? Water Absorption : Roots absorb water from the soil through osmosis. Cohesion and Adhesion : Water molecules stick together (cohesion) and to the walls of xylem vessels (adhesion), forming a continuous column. Evaporation : Water evaporates from the mesophyll cells into the air spaces within the leaf and exits through the stomata. Negative Pressure : The loss of water creates a negative pressure (tension) that pulls more water into the leaf from the xylem. Upward Movement : This tension pulls the continuous column of water upward from the roots through the xylem vessels to the leaves. This entire process is passive, relying on physical forces rather than ...
