Question
The cell (plasma) membrane is often described as ____.
Answer
The cell (plasma) membrane is often described as a semipermeable phospholipid bilayer.
Note: When forming bilayer membranes, the polar heads of phospholipids are able to face toward the watery environment within and outside the cell, while the tails create a nonpolar inner layer within the membrane, creating a barrier to polar molecules that allows the regulation of their passage in and out of the cell.
