Solution

The correct option is A Singer and Nicolson
  • The fluid mosaic model of the biomembrane or cell membrane was proposed by SJ Singer and GL Nicolson in the year 1972.
  • According to this model, the protein molecules are embedded in the lipid bilayer.
  • Thus, the proteins are seen as icebergs in the sea of lipids.
  • It is the most acceptable model of the plasma membrane and its main function is to provide shape to the cell.
  • The lipid bilayer of the cell membrane provides fluidity, flexibility and elasticity to the membrane.
  • So, the correct answer is 'Singer and Nicolson'.
