Water helps cells to keep their form. Water as a solvent dissolves salts, sugars, proteins, and many other substances that are used in the process of metabolism and the digestion of food. Water also allows the transportation of bodily wastes, and the support of a stable body temperature through perspiration and evaporation. Although water is very helpful and has hardly any dangerous effects, too much water can be dangerous. One way organisms gain water is through food, and by respiration.
Organisms lose water thmugh evaporation, urinating, and by osmosis.
Water is used in so many different ways. It is hard to believe that this compound came from only two elements. Water looks so simple when we drink it, or when we use so much of it to wash our cars or take showers, but there are so many things that water does. There is so much of this compound, but without it there would be no life. I think too many people look over the importance of water and take it for granted.
