Cell membrane

A cell membrane, plasma membrane or plasmalemma is a selectively permeable lipid bilayer coated by proteins which comprises the outer layer of a cell.

The plasma membrane works between the machinery on the inside of the cell and the outside fluid that bathes the cells.

The plasma membrane lets nutrients into the cell such as glucose, amino acids, and lipids.
