The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment.
Q) How does it protect us? The cell membrane allows or permits the entry and exit of some materials in and out of the cell. It also prevents the movement of some other materials. The cell membrane, therefore, is called a selectively permeable membrane.
