The hydrophilic heads of phospholipids in the cell membrane attract water molecules. These heads have a charge that interacts with the polar water molecules, allowing them to form hydrogen bonds with the water. This hydrophilic property helps create a stable structure for the cell membrane.
The phospholipid bilayer of the cell membrane is typically in contact with the interstitial fluid. This layer consists of polar head groups facing outward, interacting with the fluid, while the nonpolar tails face inward, forming a barrier for the cell.
