If a plant is kept covered with a polythene sheet, we notice some water drops on the inner side of the sheet after sometime due to transpiration. The loss of water in the form of vapour from the aerial parts of the plant is known as transpiration. This process helps in the absorption and upward movement of water and minerals dissolved in it from roots to the leaves. It also helps in temperature regulation.
