Water's polarity lets it stay liquid at room temperature. Most molecules of water's size are gas, but because water molecules attract each other they are connected by polar bonds that cause it to be liquid. Also, its polarity make it a solvent. Molecules connected ionically get separated when introduced into water. This is why salt disolves in water, literally because the water breaks up the ionic bond between the Sodium and Chloride. Also, water's ionic nature is what lets it move up the roots and stems of plants and into the leaves. This process is similar to how if you place the edge of a paper towel in water the water moves up the paper towel inspite of gravity.

Hydration is essential for survival, and the chemical polarity of water allows living organisms to do a variety of things - for example, temperature regulation. If the body gets too hot, the pores in the skin perspire thus releasing heat, and sweat obviously contains water. Without it, the body would overheat and fail to function.

the polarity of water determins what can and cannot dissolve in it. for example, water is polar and oil is non-polar. this is why we can not mix oil and water.

How does the polarity of water assist the movement of molecules?

The movement of molecules are very important on earth, and they happen in and on every living organism. (totally wrong above this) Think of water molecules as magnets; each with an opposing pole. Like magnets, water molecules repel each other when two parts of the same pole are pushed together. The polarity of the water does the same thing, pushing the molecules apart.
