The fluid mosaic model describes the plasma membrane of animal cells as a mosaic of components—including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Proteins are not covalently bonded to the lipid bilayer, nor do they form or coat an inner layer of lipids; instead, they float within or on the lipid bilayer, allowing the membrane to maintain fluidity and flexibility.
