The cell membrane is sometimes referred to as the fluid mosaic model because A. Many small pieces make a single moving design (i.e. proteins arranged spread out like a mosaic).
The cell membrane, also known as the plasma membrane, is a thin structure consisting of two layers of lipids (lipid bilayer). Among the lipids consist of integral proteins and peripheral proteins arranged in a mosaic that surrounds a cell and each is inserted between two layers of lipids of a fluid consistency. Lipid molecules in cell membranes are amphiphilic, that is, they have a hydrophilic (polar) group on the head and a hydrophobic (non-polar) group on the tail. The cell membrane also consists of oligosaccharides, glycolipids, and cholesterol. Cholesterol is between the phospholipid molecules, and its presence can be reduces the fluidity of the cell membrane.
