What is transpiration in plants?

Transpiration in plants refers to the movement of water from the soil through the plant to the atmosphere. This process begins with water being absorbed by plant roots from the soil. The water then travels up through the plant’s vascular system, primarily the xylem vessels, and exits the plant through tiny openings in the leaves called stomata. During this process, water evaporates into the atmosphere, which is crucial for the plant’s internal water regulation, cooling, and nutrient transport.
