The Fluid Mosaic Model. Cell structures are located within the cytoplasm of a cell. In every plasma membrane lies a structural framework of different components with significant cellular functions making up a mosaic known as the fluid mosaic model.

While initially proteins were considered to form thin sheets on either side of the membrane bilayer the fluid mosaic model considered the presence of globular proteins as an integral part of membrane structure.
