Answer
During transpiration, water is first absorbed by plant roots from the soil. This water travels through the plant’s vascular system (xylem vessels) and reaches the leaves. In the leaves, water moves into the stomata, small pores on the leaf surface, and evaporates into the atmosphere as water vapor. This evaporation creates a negative pressure within the plant, which helps draw more water from the roots through the plant. Transpiration also helps in cooling the plant, maintaining its water balance, and supporting the uptake of essential nutrients.
