The Cell Membrane is a Fluid Mosaic. A cell is the basic unit of life, and all organisms are made up of one or many cells. One of the things that all cells have in common is a cell membrane. It is a barrier that separates a cell from its surrounding environment. This outer boundary of the cell is also called the plasma membrane.
The term fluid mosaic model refers to the theory that describes a plasma membrane. Think about what the words mean. Fluid: it is not a solid or a gas. Mosaic: It is made up of tiny different pieces.You could think of it behaving like a pool with a layer of ping pong balls floating on it.ideways swapping occurs very frequently, while swapping between the two layers is less frequent mosaic refers to the collage of intrinsic proteins that stud the membrane. the diversity of protein channels and carriers, together with their unique marker capabilities by association with glycocalyx, makes it mosaic like.
