"The Importance of Water and its Properties for Living Organisms" Next to oxygen, water is essential for all living organisms on Earth. It is a major component in cells, which make up all living organisms; therefore approximately 60% to 95% of living organisms are water. Water molecules are dipolar (meaning that its electrons are not shared equally due to covalent bonding) and this generates hydrogen bonding between atoms. As a result its structure gives water many important properties such as its thermal, high surface tension, incompressibility and cohesiveness, which give it many useful biological roles such as being a solvent, a coolant, an insulator, as support, a lubricant and a reagent. Moreover water is used in chemical reactions, transporting and it provides a suitable environment for aquatic animals to habitat. There are a few thermal properties, which are very important for living organism. Since water molecules have a...
