Question

cell city analogy
in a far away city called grant city, the main export and production product is the steel widget.
everyone in the town has something to do with steel widget making and the entire town is designed
to build and export widgets. the town hall has the instructions for widget making, widgets come in
all shapes and sizes and any citizen of grant can get the instructions and begin making their own
widgets. widgets are generally produced in small shops around the city, these small shops can be
built by the carpenters union (whose headquarters are in town hall).

after the widget is constructed, they are placed on special carts which can deliver the widget
anywhere in the city. in order for a widget to be exported, the carts take the widget to the postal
office, where the widgets are packaged and labeled for export. sometimes widgets dont turn out
right, and the
ejects\ are sent to the scrap yard where they are broken down for parts or destroyed
altogether. the town powers the widget shops and carts from a hydraulic dam that is in the city. the
entire city is enclosed by a large wooden fence, only the postal trucks (and citizens with proper
passports) are allowed outside the city.

match the parts of the city (underlined) with the parts of the cell.

1. mitochondria

1. ribosomes

1. nucleus

1. endoplasmic

reticulum

1. golgi

apparatus

1. protein

1. cell membrane

1. lysosomes

1. nucleolus

Explanation:

1. Mitochondria: The hydraulic dam powers the city, similar to how mitochondria produce energy (ATP) for the cell. So Mitochondria - Hydraulic Dam.
2. Ribosomes: Small shops make widgets, and ribosomes make proteins. So Ribosomes - Small Shops (where widgets are produced).
3. Nucleus: Town hall has instructions for widget making, nucleus has genetic instructions (DNA) for the cell. So Nucleus - Town Hall.
4. Endoplasmic Reticulum: Special carts transport widgets, ER transports proteins. So Endoplasmic Reticulum - Special Carts.
5. Golgi Apparatus: Postal office packages and labels widgets for export, Golgi modifies, sorts, and packages proteins. So Golgi Apparatus - Postal Office.
6. Protein: Widgets are the product made, proteins are the product of the cell's production. So Protein - Steel Widget.
7. Cell Membrane: Large wooden fence controls what enters/leaves the city, cell membrane controls what enters/leaves the cell. So Cell Membrane - Large Wooden Fence.
8. Lysosomes: Scrap yard breaks down rejects, lysosomes break down waste/debris in the cell. So Lysosomes - Scrap Yard.
9. Nucleolus: Carpenter's union headquarters (in town hall) is like nucleolus (in nucleus) which is involved in ribosome production. So Nucleolus - Carpenter's Union Headquarters.
