Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the
fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two
nonpolar (hydrophobic) tails.
Review
The cell membrane is sometimes referred to as
the _____________________. The cell membrane is
made up of two layers of
________________________, with many
______________ imbedded throughout to help
transport molecules in/out of the cell.
Each phospholipids has a ____________ head
facing out, and 2 non-polar ________ facing in.
