Life is not possible without water. Many life processes are dependent on water to function, but why is that? The answer is in its chemistry, the unique qualities and properties of water are what make it so important and basic to life. Water is an excellent solvent, so it can dissolve nutrients in our bloodstream. It holds its temperature so well, due to thermal capacity, so life in lakes and ponds don’t die when the air temperature drops at night. It also supports cellular structure, ensuring cells hold their shape.
