Describe the fluid mosaic model of plasma membrane

The fluid mosaic model explains various characteristics regarding the structure of functional cell membranes.

According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which proteinmolecules are embedded. The phospholipid bilayer gives fluidity and elasticity to the membrane.

Small amounts of carbohydrates are also found in the cell membrane. The biological model, which was devised by Seymour Jonathan Singer and Garth L. Nicolson in 1972,^[1] describes the cell membrane as a two-dimensional liquid where embedded proteins are generally randomly distributed.

For example, it is stated that "A prediction of the fluid mosaic model is that the two-dimensional long-range distribution of any integral protein in the plane of the membrane is essentially random."^[1]
