The Biological Importance of Water In Living Organisms Water is the most important molecule in cells‚ the whole organisms and on earth‚ this is due to it’s unique physical and chemical properties. ” A water molecule‚ because of its shape‚ is a polar molecule. That is‚ it has one side that is positively charged and one side that is negatively charged”(1).
