The nucleus is like a town hall because it controls the actions of the cell and contains important instructions, or files, for making other structures and materials.

The mitochondria is like a power house because it converts chemical energy into compounds for the rest of the "city" to use.

The vacuole is like a storage tank or reservoir because it stores certain materials, such as food molecules and enzymes. Plant cells contain a large central vacuole filled with liquid, which helps maintain the plants' rigidity.

The cytoskeleton of a cell is like a construction or engineering company because the materials they use to build structures must be able to protect the building.

A vesicle is like a city's transportation system because it transports materials throughout the cell, much like a bus transports people.

Lysosomes are like garbage trucks and trash dumps because they take care of the outlived organelles and keep the cell clean, just like a city.

The Golgi apparatus like a post office because it sends materials to other parts of the "city" after sorting and packaging them.

Ribosomes are like factories because they make proteins for cell use, much like a factory producing goods for its citizens.

A rough endoplasmic reticulum is like a customization shop because they both involve modifications of materials and products to then be transported to the post office, or Golgi apparatus.

The smooth endoplasmic reticulum is like a toxic waste facility because, like a facility, the smooth endoplasmic reticulum breaks down toxins. A toxic waste facility disposes toxins that threaten the city, by neutralizing them.

A centriole is like a town hall because in order for a cell to divide or relocate, it must get approval from the nucleus, or the city hall. Like the town hall, the centriole would assist the city hall, or the nucleus, in performing this task.

The cell membrane is like the city's border control because, just like cell membranes, the border control regulates who can enter or exit the city.

The chloroplasts of a plant cell is like a solar panel plant because they convert the energy from the sunlight, like solar panels, into food molecules through photosynthesis.

A cell wall in a plant cell or prokaryote is like a defensive wall because they both offer protection and support. Both cell walls and defensive walls are both used as borders between other cells and cities. Cell walls provide rigidity in plant cells.

The cytoplasm is like a network of streets because, like streets, the cytoplasm contains "blocks" and "neighborhoods," including many structures, or organelles. Materials transported in and out of the cell travel through the cytoplasm to get to their final destination.

The flagella and cilia are like trucks because they both transport materials or relocate things to other cities.

Microfilaments are also like construction sites because both involve the construction of strong materials in order to create a building or structure.

Microtubules are like the pipes of a city because they both help groups of structures maintain their shape.
