What is the name of the model for the membrane proposed by Singer and Nicholson in 1976?

The model proposed by Singer and Nicholson in 1976 is known as the "fluid mosaic model." This model describes the cell membrane as a dynamic structure in which various proteins float in or on the fluid lipid bilayer, creating a mosaic of components. It emphasizes the flexibility and fluidity of the membrane, allowing for the movement and interaction of different molecules within it.
