Fluid Mosaic Model:

  • It was proposed by Singer and Nicolson in 1972. 
  • With recent modifications, it is the most accepted model for the structure of plasma membrane. This model provides for a core of a lipid bilayer which maintains the fluidity of the plasma membrane. 
  • The greater the concentration of unsaturated fatty acid residues, the more fluid is the bilayer. The mosaic nature of the plasma membrane is due to its protein content.
  • The plasma membrane is quasi fluid structure. The lipids perform the following movements:

               rotational movement 

               lateral diffusion movement

               flip-flop movement / transversion movement (rarely shown) 

  • The proteins perform the following movements:

                rotational movement 

                lateral diffusion movement

The proteins provide the fluidity to the plasma membrane.
