Acell membrane is a phospholipid bilayer that has polar and nonpolar areas on both sides of the membrane are aqueous (water based) fluids what is an important function of the phospholipid in the cell membrane a) the heads keep water away from the tails b)the polar areas of the phospholipids give the cell an electrical charge c)the phospholipids produces wax to keep water out of the cell d) the phospholipids the cell maintain its internal aqueous enviroment
