Quizplus · Accepted Answer

The fluid-mosaic model describes a cell membrane as a phospholipid bilayer with the nonpolar tails oriented towards the interior of the membrane. This forms a hydrophobic barrier that separates the inside of the cell from the surrounding fluid. The model also includes various proteins and other molecules embedded within the membrane, forming a mosaic-like structure. There are not three layers of phospholipids, nor are the nonpolar sections of the membrane oriented to the outer surface.
