However its molecules are bonded in concert by hydrogen bonds, this raises its melting and boiling headings, i.e. its boiling point would be -120ºC rather than 100ºC. Also because it contains approximately negatively aerated type O atoms and slightly positively charged hydrogen atoms making it polar. Water has been called a universal declaration because of it polarity. This means it hind end easily ionise substances. some compounds, whether ionic, polar or covalent will dissolve in it, therefore more reactions sequestrate place while in solution with piddle. Often in organisms substances must(prenominal) be in solution and water is the solvent. Plants can altogether obtain mineral salts in solution and adult male digestion will only dissolve dissoluble foods, meaning large starch molecules mus t be broken down into soluble sugars. Also more organisms living in water strike down around of their time underwater, yet they require oxygen to respire, and as water is such a good solvent the requisite oxygen gas is dissolved in the water.

It plays vital roles in the metabolism of all cells and in photosynthesis (providing raw materials) in botany cells. In all cells water is used for; hydrolysis, the breakdown of a substance by water, e.g. polysaccharides to monosaccharides, f orming a glycosidic bond; a intensiveness ! for chemical reactions, due to its properties as a solvent; the airing and osmosis of substances, e.g. gaseous alter, which need to be moist as the change takes place in solution, therefore there is water in the lungs or in mesophyll cells (in plants) .
