Plants release water to the air through leaves in a process called?

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

Answer: (A)

Transpiration is the process by which water absorbed by a plant’s roots is pulled up through the plant and released as water vapor from the leaf surfaces, mainly through openings called stomata. This is how leaves lose water to the air and also why water can move from roots to leaves in the first place—the evaporation of water from the leaf creates a pull that helps draw more water up the stem. Transpiration also cools the leaf and is influenced by factors like humidity, temperature, wind, light, and soil moisture. The other terms describe different parts of the water cycle: evaporation is water turning into vapor from surfaces, condensation is vapor turning back into liquid, and precipitation is rain or snow that falls to the surface.
