The cell membrane or plasma membrane is an important part of a cell. The main functions are listed below.

1. It is selectively permeable, many molecules can move passively but polar molecules need a carrier protein for transportation.
2. Maintains the shape of the cell.
3. Protects the integrity of the interior of the cell by allowing certain substances inside.
4. Physical barrier and mediate the cellular extracellular activities.
