Biological Importance of Water for Living Organisms Water is made up of two elements‚ 2 positively charged hydrogen molecules and one negatively charged oxygen molecule. Water molecules have uneven charge distribution as one end of the molecule is slightly positive and the other slightly negative‚ this is called polar. Ionic substances such as sodium chloride dissolve easily in water because the positively and negatively charged ions are separated due to the dipole nature of water. As water is dipolar

The biochemical importance of water Sam Ellick 13/11/2010 Water otherwise known as H2O is a necessity for life to exist. It has many unique features compared to other molecules of its size. For example solid ice is less dense than liquid ice‚ which ponds and lakes freeze from the top down. This is important in insulating the aquatic life in the winter. This essay however will be looking at why water is so important in biochemical terms. Its shape Water‚ as its formula H2O suggests‚ consists

The Biological Importance of Water Water is perhaps the most important molecule for the survival and life of organisms. On the surface of the planet there is obviously much more area of water than land‚ which shows its significance. The fact that water makes up 60-95% of all living organisms shows the incredible biological importance of water. Water has many uses and roles‚ one of them it being used as a support unit in plants. The uptake of water by plant cells creates a pressure against the rigid

IMPORTANCE OF FRESH WATER All living things on Earth need fresh water in order to survive But human beings become ill and may even die if they cannot get pure or clean and are forced to drink polluted water. Human beings can only last 3 day without fresh water. People died of thirst after the cyclone in 1999 because their supply of fresh water from irrigation channels was destroyed form tidal waves.

not exist without water. Seventy-five % of the Earth is covered in water providing an environment for organisms to live in. the water molecule is made up of two hydrogen atoms and one oxygen atom. As oxygen atoms are more electronegative that hydrogen atoms the electrons shared covalently between the oxygen and the hydrogen atoms tend to spend more time near the oxygen atom making it partially negative and making the hydrogen atoms partially positive. The partial charges in the water molecule allow
