• The cell membrane is made out of two layers of phospholipids, a type of lipid with a head and two tails. These molecules' structure allows the membrane to be semi-permeable, meaning only certain molecules can cross the membrane. This is important as cells need to quickly gets things like oxygen and water, and get rid of wastes like carbon dioxide.
