Explanation;
-The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components; including phospholipids, cholesterol, proteins, and carbohydrates; that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.
-The Fluid Mosaic Model states that membranes are composed of a Phospholipid Bilayer with various protein molecules floating around within it. The Fluid part represents how some parts of the membrane can move around freely, if they are not attached to other parts of the cell. The mosaic part illustrates the ‘patchwork’ of proteins that is found in the Phospholipid Bilayer.
