The nucleus is like the city hall because it controls everything in the cell. The city hall is the control center for the city.

The cell wall gives the cell it's shape. The lines around the city define the city boundaries. Which gives the city it's shape.

Chloroplasts convert light energy. Solar panels do this for many houses in the city

The nucleolus is the site where the ribosomes are made. The city council is where the city official.

Ribosomes make proteins. The city officials make the rules. Proteins are like rules because they keep the body on track.

Vesicles transport materials within the cell, and U-Haul trucks transport materials around a city.

Golgi apparatus packages proteins for transport out of the cell. The post office packages mail to be shipped out of the city.

Lipids store energy like batteries and the endoplasmic reticulum produces lipids, so the endoplasmic reticulum is like a battery factory.

The cytoskeleton is a network of protein fibers and the pipes are a network of plumbing.

The rough ER transports proteins to make the cell better. Hospitals make the people better.

The cytoplasm is the fluid that fills the cell and the citizens are the people that fill the city.

The chromatin are like medical records in a hospital because they are a collection of DNA.

The police regulate what comes in and out of the cell, like police do for the city.

Like the city's storage units, vacuoles store materials within the cell.

Mitochondria produce usable forms of energy for the cell. Telephone poles provide energy for the phones in the city.
