  Cell Membrane Structure and Transport Mechanisms | NEET Biology Notes Fluid Mosaic Model showing membrane structure, transport mechanisms, and cell wall components important for NEET Biology.  - Dr.Sanjaykumar Pawar  Cell Membrane (Fluid Mosaic Model) – Easy NEET Notes (Line by Line) 1. Fluid Mosaic Model (Singer and Nicolson, 1972) Original Line: "An improved model of the structure of cell membrane was proposed by Singer and Nicolson (1972) widely accepted as fluid mosaic model." Easy Note: In 1972 , Singer and Nicolson proposed the Fluid Mosaic Model . It is the most accepted model of cell membrane structure. It explains how lipids and proteins are arranged in the membrane. NEET Point: Fluid Mosaic Model = Singer and Nicolson (1972) Original Line: "According to this, the quasi-fluid nature of lipid enables lateral movement of proteins within the overall bilayer." Easy Note: Cell membrane is made mainly of a lipid bilayer . Lipids are not fi...
