The properties and biological importance's of water to living organisms Water is a simple molecule, yet it is fundamental to life. In active living cells, two-thirds, or often more, of the area is occupied by water, and two-thirds of the globe is covered in water. Water is therefore extremely abundant, and in biological terms it has great importance both inside cells, and externally, for example as a habitat The simple molecule of H2O has many interesting physical and chemical properties which contribute to its importance. It is the only substance which can be found naturally in all three states - solid (ice), liquid and gas (water vapor). Water molecules bond to each other by means of hydrogen bonds, and this raises its melting and boiling points substantially. If these bonds did not exist, its boiling point would be in the region of -120C, rather than the actual value...
