It describes the structure of cell membranes formed by phospholipids, highlighting their hydrophilic heads and hydrophobic tails that create a lipid bilayer. This bilayer acts as a barrier while enabling selective passage of substances through embedded proteins that assist in the movement of specific ions and molecules.
