What is the process by which plants release water vapor from their leaves called?

Answer and explanation

Correct answer: Transpiration

Direct answer: B, transpiration. Plants absorb water mainly through their roots and transport it through xylem to the leaves. A large part of this water eventually leaves the plant as water vapour, usually through tiny openings called stomata on the leaf surface. This loss of water vapour is called transpiration. It is different from respiration, which is the release of energy from food in cells. Photosynthesis uses light energy to make food from carbon dioxide and water; it is not the name for water-vapour loss. Absorption is the entry of water or minerals into the plant, mainly through roots, not their release from leaves. Memory cue: transpiration is like plant perspiration, but it is not exactly the same as sweating in animals.
