Answer
S.J. Singer and Garth L. Nicolson proposed the fluid mosaic model of the plasma membrane in 1972. This model describes the cell membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that can move laterally, creating a mosaic-like pattern. The "fluid" nature refers to the flexible, liquid-like consistency of the lipid layer, while "mosaic" describes the diverse arrangement of proteins and other molecules within the membrane.
