The membrane is made out of several molecules - mainly phospholipids. Instead of being a rigid structure, the molecules within the membrane are constantly moving and changing places. This means the membrane appears like a fluid.
This is the cell membrane or plasma membrane which is made of a phospholipid bilayer.
Simply put, the fluid mosaic model is a description of the membrane of a cell. The fluid part refers to the phospholipids of a cell membrane, which, like liquid, flow. The mosaic part refers to proteins embedded in the phospholipid bilayer that act as conduits through which molecules enter and exit the cell.____________The currently accepted model of cell membrane structure, which envisions the membrane as a mosaic of individually inserted protein molecules drifting laterally in a fluid bilayer of phospholipids.Fluid mosaic is a term used to describe the current model of the cell membrane.Cell membranes are basically double layers (bilayers) of molecules called phospholipids. 'Floating' in the phospholipid bilayer are molecules of protein. a mosaic is a structure made up of many different parts. Viewed from above the membrane would look something like a mosaic - a 'sea' of lipid with many 'islands' of protein.The lipid bilayer is not rigid, and the lipid and protein molecules are able to move sideways in the membrane i.e. the membrane is fluid.This model of the cell membrane was proposed by Singer and Nicolson in 1972, and has been supported by many experiments since then.model for cell membrane given by SJ singer and GL Nicholoson
plasma membrane is made up of phospholipids,proteins and short carbohydrate chains.still the structure not visible.so there are several models which explains arrangement of these components.the most accepted is the fluid mosaic model

fluid- it moves around and is not staying in one place (not solid) mosaic- made of many different kinds of macromolecules and is not the same all around

The cell membrane is sometimes referred as "mosaic" because is a work of art made of individual tiles or other pieces assembled to form a picture or design.
The plasma membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid, but more like a 'fluid'. The membrane is depicted as mosaic because like a mosaic that is made up of many different parts the plasma membrane is composed of different kinds of macromolecules, such as integral proteins, peripheral proteins, glycoproteins, phospholipids, glycolipids, and in some cases cholesterol, lipoproteins.
A picture made with with tiles and stone is a mosaic.
The cave canem mosaic was made of marble tiles (tesserae).
The Cave Canem (beware of the dog) mosaic was made of marble tesserae (pieces).
