Which process describes the transformation of water from liquid to vapor in plants?

The transformation of water from liquid to vapor in plants is best described by the process of transpiration. This process occurs when water absorbed by plant roots moves through the plants and is released as water vapor from tiny openings in the leaves called stomata. Transpiration is vital for plants as it helps to regulate temperature, facilitates nutrient uptake, and maintains plant hydration.

While evaporation refers to the process of liquid water turning into vapor, it does not specifically denote the process as occurring in plants. Condensation is the opposite process, where water vapor cools and turns back into liquid, and precipitation involves water falling from the atmosphere in forms such as rain, snow, or hail. Thus, transpiration is the correct term when discussing water vapor release from plant leaves.
