The currently accepted hypothesis of membrane structure is referred to as the fluid mosaic model, and was proposed by Singer and Nicholson in 1976. The most prominent element of the cell membrane is a fluid bilayer of lipids, in which a number of proteins are embedded.

The cell membrane is semi-permeable which means that it allows some materials to pass through and not others. This allows the cell to maintain a stable internal environment known as homeostasis. The cell membrane, also called the plasma membrane, is made mostly of lipids. The lipids found in cell membranes are specifically called phospholipids.
