Composition of the Cell Membrane & Functions: The cell membrane is also called the membrane and is made of a phospholipid The phospholipids have a (water attracting or polar) head and two (water repelling or non-polar) The head of a phospholipid is made of an alcohol and phosphate group, while the tails are 2 chains of fatty acids. Phospholipids can move apart and allow water and other molecules to pass through into or out of the cell. This is known as simple because it does not require and the molecules are moving from areas of concentration to an area of concentration. 1.
