Question

Briefly explain, how transpiration helps in upward conduction of water in plants?

Answer 1

• As a result of transpiration, a suction force is created in the xylem vessel. This force causes water to be pulled up from the xylem in the roots to the stem and leaves. This pulling force is called transpirational pull.
• Whenever the xylem lay empty, e.g., during transpiration, the water from below rises into them by a capillary force.
