Quizplus · Accepted Answer

The fluid-mosaic model describes a cell membrane as having two layers of phospholipid molecules with their nonpolar sections oriented to the inside of the membrane, creating a hydrophobic environment for the cell's contents. The model also includes various types of proteins and other molecules that are embedded in or attached to the membrane, creating a mosaic-like pattern. There are not three layers of phospholipids and the nonpolar sections are not along the outer surface of the membrane. A single row of phospholipid molecules would not be sufficient to form a barrier between the inside and outside of the cell, and two layers of proteins do not separate the contents inside a cell from the surrounding fluids.
