A car is enclosed in a metallic body casing to hold its shape and prevent the internal contents from falling off. Similarly, a cell is enclosed in a cell wall that holds its shape and acts to prevent entry of unwanted substances into the cell.

The cell membrane functions like the doors and windows of the car that allow entry and exit of substances. Just like a car needs a driver to control it, an animal cell has a nucleus that controls the cellular activities. The trunk of a car is used to store luggage; a function that is similar to that of the vacuoles which store water, food and waste products. The Golgi apparatus that supply substances within the cell function like the pipes and tubes of the car. The mitochondria function like the car engine to provide energy required to propel the car.

Despite their similarities, a car and a cell have vast differences. Cells replicate and multiply to form similar cells in the process of growth and development. This is contrary to a car that cannot replicate or multiply biologically. A cell can also undergo modification when trying to adapt to physical and chemical changes, something that a car cannot do.
