The water content in living organisms is 60-75% of their mass. However, there are organisms or organs and tissues where this percentage is more – jellyfish 98% of body weight or less – bone tissue 22%. Water is the medium of many metabolic processes. It is water that determines the volume of cells and intracellular (turgor) pressure. Withering of plants occurs when the amount of water evaporated by plants is greater than the amount of water entering them from the soil. When wilted, the leaves lose their elasticity, become soft; the upper, young parts of the stems go down.
