What is the "big idea" of the fluid mosaic model of plasma membranes?

• the plasma membrane creates a specialized FLUID that looks like a MOSAIC.

• the plasma membrane is a MOSAIC.

• the fluid mosaic model is NOT related to the plasma membrane.

• a plasma membrane is a MOSAIC of components that move FREELY and FLUIDLY.

What is this image?
