The plasma membrane is made up of two layers of molecules. One end (the phosphate head) is polar and is in contact with the aqueous (watery) fluid both and the cell. Therefore this region is said to be. The interior of the membrane contains tails made of fatty acids and do not interact with the aqueous fluid. The plasma membrane also contains two broad groups of membrane proteins. The first are proteins that penetrate into the phospholipid bilayer. (Some that go all the way through from one side to the other are called proteins. The second group are proteins that adhere to one side of the membrane.

In cell membrane, phosphate head groups? Face both the extracellular environment and the cytoplasm only face the extracellular environment bind each other via ionic bonds in the interior of the membrane only face the aqueous cytoplasm

Membrane phospholipids are able to drift about in the plasma membrane. They have hydrophobic heads that face the center of the membrane and are shielded from water. They remain fluid because they are lightly packed against one another. They have hydrophilic tails that face outward and are exposed to water.
