What is the process by which water moves from a plant’s leaves back into the atmosphere?

• A. Transpiration
• B. Evaporation
• C. Condensation
• D. Precipitation

Answer: (A)

Transpiration is the process by which water moves from a plant’s leaves back into the atmosphere. Water absorbed by the roots travels up through the plant and reaches the leaves, where tiny openings called stomata let water vapor escape. This water loss helps pull more water up from the roots and is a normal part of how plants exchange gases and regulate temperature. Evaporation is water turning into vapor from any surface, condensation is water vapor turning into liquid droplets, and precipitation is rain; these other processes aren’t the plant’s method of releasing water from its leaves.
