what is the term used to describe the cell membrane
Remember these key points: 1  Cell membranes or plasma membranes consist of a phospholipid bilayer with proteins embedded in the membrane. 2  Most of the functions of plasma membranes are handled by the proteins. 3  This arrangement of proteins and phospholipids is often called the fluid mosaic model for a cell membrane.he Actual Cell membrane has proteins embedded in the lipid bilayer. Embedded in the phospholipid bi-layer are a diverse set of proteins which do most of the important functions of the cell membrane. This idea is called the fluid mosaic model of the cell membrane.
