<P> The cell membrane ( also known as the plasma membrane or cytoplasmic membrane ) is a biological membrane that separates the interior of all cells from the outside environment . The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells . The basic function of the cell membrane is to protect the cell from its surroundings . </P>
