Plasma Membrane or Cell Membrane
Each cell is bounded by an extremely delicate, thin, elastic, living membrane, called the plasma membrane. It is about ten thousandth of a millimetre in thickness. In plant cell, it is present on the inner side of the cell wall. The plasma membrane is made up of two layers of lipid (fat) molecules with protein molecules sandwiching it and embedded in it. Plasma membrane is a selectively permeable membrane which allows the flow of only some substances into the cell and out of the cell. Thus, it helps in maintaining the distinct chemical composition of the cell.
