The plasma membrane is a fluid mosaic. This means that it is flexible and made up of many different types of molecules. Phospholipids form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for
1 Features of the fluid mosaic modelâ¢ Membrane is bilayer of phospholipid molecules that move about by diffusion within their own monolayerâ¢ Phospholipid tails point inwards and form a non-polar hydrophobic interior.he fluid mosaic model of membrane structure. 1  1.
