Cell membrane

The cell membrane is also called the plasma membrane, plasma lemma or "phospholipids bilayer" is a semipermeable lipid bilayer frequent to all living cells. It contains a variety of biological molecules, primarily proteins and lipids, which are concerned in a vast array of cellular processes, and also serves as the attachment point for both the intracellular cytoskeleton and, if present, the cell wall.Robert Hooke was the first to name the parts of cells, as well as the plasma membrane.
