Detailed explanation-1: -The fluid mosaic model describes the cell membrane as a tapestry of several types of molecules (phospholipids, cholesterols, and proteins) that are constantly moving. This movement helps the cell membrane maintain its role as a barrier between the inside and outside of the cell environments.

Detailed explanation-2: -The “mosaic” term of this model refers to the mixture of lipids and intrinsic proteins in the membrane. These boundaries are also “fluid” because their components can move laterally, allowing both diffusion of components and local specific gatherings.

Detailed explanation-3: -The fluid mosaic model was first proposed by S.J. Singer and Garth L. Nicolson in 1972 to explain the structure of the plasma membrane.

Detailed explanation-4: -The fluid mosaic model is a way of describing the structure of cell membranes. The model likens the membrane to a “mosaic” of different components, consisting of a fluid or elastic double layer made up of lipid molecules and large protein molecules.
