Fluid mosaic model of plasma membrane explain
WebMay 5, 2024 · The fluid mosaic model is a model of the cell membrane. It can be described with various analogies, such as a moat or double layered barrier with guards that decide what may enter and exit the cell. WebApr 3, 2024 · The fluid mosaic membrane says that the plasma membrane is a mosaic which is made up of phospholipids, carbohydrate and cholesterol and the protein gives the membrane a fluid character. The proteins present are called the globular protein which is of two types- Intrinsic and extrinsic.
