उत्तर
Transpiration helps in the upward conduction of water in plants through the transpiration pull mechanism. As water evaporates from the stomata of leaves, it creates a negative pressure (suction force) in the leaf cells. This draws water upward from the xylem vessels in the stem and roots. The cohesive and adhesive properties of water molecules help maintain a continuous column of water, allowing it to move against gravity from the roots to the leaves. This process is essential for nutrient transport and maintaining plant hydration.
