Cell Membrane: Forms the outer boundary of the cell. Regulates the passage of materials in and out of the cell. aids in protection and support.
The wall of a race track is like the cell membrane is regulates what comes in because nothing can go through the wall and it stops the when it hits the wall. It can also protects them because at some race tracks they have foam behind the wall and that help absorb the pressure of the car and so the car doesn't hit the wall as hard.
