Hydrophilic molecules are attracted to water, so phospholipids that are hydrophilic will also be attracted to water. This property allows the phospholipids to form a bilayer structure in the cell membrane with the hydrophobic tails oriented towards the interior of the bilayer and the hydrophilic heads oriented towards the exterior, where they can interact with the watery environment inside and outside the cell.
