Describe the basic structure of the cell membrane with regard to specific molecules. What is it made out of?

The cell membrane is made up of phospholipids and the overall name is the Phospholipid bi-layer

Explanation:

The cell membrane has two rows of phospholipids.  A phospholipid is broken into two parts, the heads and tails.  The heads are hydrophilic (water-loving) and point to the outside and inside regions making the inner and outer wall, while the tails are hydrophobic (water-hating) and face each other to make the inside of the membrane.  There are also molecules of cholesterol and proteins throughout the membrane.
