Which process is water evaporating specifically from plants or leaves when energy is added?

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

Answer: (A)

Transpiration is the evaporation of water from plant surfaces, mainly leaves, when energy such as heat or light is added. In the leaf, water moves to the moist surfaces and escapes as water vapor through openings called stomata. This not only cools the leaf but also helps pull water up through the plant’s xylem for nutrient transport. Evaporation, in contrast, is the general process of a liquid turning into vapor from any surface. Condensation is vapor turning back into liquid, like dew forming on surfaces. Precipitation is water that falls to the surface as rain, snow, or hail. So the scenario described matches transpiration.
