Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 99-99.5% is lost by transpiration. Leaf surfaces are dotted with pores called stomata, and in most plants they are more numerous on the undersides of the foliage.
Transpiration is the process in which plants release water back into the atmosphere in the form of water vapor. In simplest terms, transpiration is the evaporation of water from plant leaves. This process occurs from the roots of the plants that carry moisture to the undersides of the leaves and is then released through the pores of the leaves back into the atmosphere. About 10% of the moisture in the atmosphere is released by plants through this process; while the other 90% come from bodies of water.
