Question: Describe the fluid mosaic model of an animal cell? Edit
Answer: Fluid mosaic model of animal cell is a model that describes structural features of animal cells.
The plasma membrane is considered as fluid as hydrophobic integral components like membrane proteins and lipids easily move sideways or laterally throughout the cell membrane. And this proves that the membrane is more like a fluid, not solid.
The plasma membrane is described as mosaic as like mosaic it also consists different types of macromolecules like peripheral proteins, lipoproteins, glycoproteins, integralproteins, glycolipids etc.
According to this model conceived by Garth Nicolson and S.J. Singer, lipid bilayers along with proteins form the base of plasma membrane. And these proteins provide more structure. The phospholipid components of the membrane can fold in itself resulting in a double layer of lipid or bilayer if placed in a polar surrounding.
This structural feature of the membrane helps it perform its functions like cell recognition and cellular transport properly. Edit
