The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell.

Functions :-

Plasma membrane is the outermost layer in cells. It separates the content of cell from their external environment. It allows the materials from surrounding to enter and exit the cell. It also allows the materials from cell to exit outside.
