Match the following:
stabilizes and maintains flexibility of cell membrane
Cholesterol
2 layers; allows small & non-polar molecules to pass through the membrane
Phospholipid bilayer
regulates what goes in and out of the cell
Plasma or Cell Membrane
allows large and polar molecules to pass through the membrane

The cell membrane, also known as the (a) membrane, is found in (b) types of cells. It controls and (c) what is allowed in and out of the cell to help maintain (d) or a balanced environment. It also is known as the (e) because the different parts of the cell membrane can move around and are not fixed in one location.
The cell membrane is made up of several components, each with their own function. The main part is the (a) , which allows small or non-polar molecules (such as (b) or steroid hormones) to pass through the membrane. Larger and polar molecules (such as (c) and sugars) are too big to pass through the phospholipid bilayers so they use the (d) to travel in or out of the cell. (e) helps make the cell membrane more rigid or loose to control what goes in and out of the cell.
