What is the biological role of water in the cell?

Water is the main component of all cells of living organisms. Even terrestrial organisms, which at first glance are able to exist only in a gaseous environment, actually live in an aquatic environment. Active cells are 60–95% water, but dormant cells are also 10–20% water. There are three forms of water in the cage:

Hydration – is located in the cytoplasm of the cell and is associated with various proteins and ions. This water is vital.
Exchange – located between protein molecules, fibers and cell membranes. First of all, it is a solvent for substances.
Free water – is in the intercellular space, vessels, organ cavities. Serves to transfer substances from the environment into the cell and makes up about 95% of all water in the cell.
