Cell membrane definition, structure/function diagram, animal/plant cell. The cell membrane is a thin flexible layer around the cells of all living things. Cell membrane, also called plasma membrane, thin membrane that surrounds every living cell, delimiting the cell from the environment around it. The membrane also contains membrane proteins, including integral proteins that go across the The bilipid membrane feature of the plasma membrane (or cell membrane) prevents the entry and exit of all molecules.

Cell Membrane Definition Simple. Simple diffusion through the lipid bilayer. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures. Its basic job is to separate the inside of cells from the outside. Most of the membrane is made up of special fatty molecules called phospholipids as well as protein molecules.
