The fluid mosaic model of cell membranes proposes that membranes are composed of a phospholipid bilayer with proteins distributed throughout. In this model: 1) Proteins are embedded within and move freely along the phospholipid bilayer. 2) The phospholipid bilayer acts like a liquid, allowing membrane components to diffuse freely. 3) Integral proteins either span the entire bilayer or are partially embedded within one leaflet of the bilayer.

Fluid mosaic model of cell membrane
protein expressed that
-Each protein spread and tucked or immersed in
a phospholipid bilayer
-Molecules of protein and fat that is not static, but
constantly moving
- Fat molecules as "liquid" on it and inside there are
protein molecules that are "swimming"
