Cell membrane definition, the semipermeable membrane enclosing the cytoplasm of a cell see more.
Think of it as a gatekeeper, guardian, or border guard despite being only 6 to 10 nanometers thick and visible only through an electron microscope, the cell membrane keeps the cell’s cytoplasm in place and lets only select materials enter and depart the cell as needed. The functions of the cell membrane of biological cells include controlling the exchange of materials between the cell and its environment this page lists the main functions of the cell membrane. Structure of cell membranes embedded in the phospholipid bi-layer are a diverse set of proteins which do most of the important functions of the cell membrane.
