what is the structure and function of the plasma membrane?
102 Membrane Structure and Function LECTURE NOTES The plasma membrane is the boundary that separates the living cell from its nonliving surroundings. Itmakes life possible by its ability to discriminate in its chemical exchanges with the environment.
Plasma Membrane Structure. The plasma membrane is composed of a phospholipid bilayer, which is two layers of phospholipids back-to-back. Phospholipids are lipids with a phosphate group attached to them. The phospholipids have one head and two tails. The head is polar and hydrophilic, or water-loving.
