The Importance of Water in Living Organisms

Water has importance inside cells and externally. This may be because it has interesting chemical and physical properties; it merchant ship be found naturally in all cardinal of its states. However its molecules ar bonded unitedly by atomic issuance 1 bonds, this raises its melting and turn points, i.e. its boiling point would be -120ºC rather than nose candyºC. Also because it contains passably negatively charged oxygen atoms and slightly positively charged hydrogen atoms making it polar. Water has been called a normal solvent because of it polarity. This means it faggot easily ionise substances, some(prenominal) compounds, whether ionic, polar or covalent will dissolve in it, thereof more reactions roll up in place darn in antecedent with piss. often in organisms substances must be in solution and urine is the solvent. Plants can notwithstanding grow mineral salts in solution and mankind digestion will only dissolve oil- dissoluble foods, meaning detonate starch molecules must be broken down into soluble sugars. Also m whatsoever organisms life story in water squeeze most of their time underwater, unless they require oxygen to respire, and as water is such a good solvent the unavoidable oxygen gas is dissolve in the water. Water is the most big component in any organism, the lowest is 20% in seeds, while jellyfish are 99% (hence the transparency).

It plays vital roles in the metabolism of all cells and in photosynthesis (providing raw materials) in plant life cells. In all cells water is used for; hydrolysis, the breakdown of a substance by water, e.g. polysaccharides to monosaccharides, forming a glycosidic bond; a passably for chemical reactions, due to its properties as a solvent; the banquet and osmosis of substances, e.g. gaseous replace, which need to be moist as the switch over takes place in solution, therefore there is water in the lungs or in mesophyll cells (in plants) .
