• Water as a thermostabilizer and thermostat. Water determines the stability of the temperature regime.
• Structural function. The cytoplasm of cells usually contains 60 to 95% water, and it is this that gives the cells their normal shape. In plants, water maintains turgor (elasticity of the endoplasmic membrane), in some animals it serves as a hydrostatic skeleton (jellyfish, roundworms). This is possible due to such a property of water as complete incompressibility.
• Water as a reagent. Water is involved in many chemical reactions: polymerization, hydrolysis, photosynthesis.
