Part E: Cell City Analogy – Match the organelle to the underling city part in the scenario.
In a far away city called Eukaryopolis, 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 carpenter's 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 don't turn out
right, and the "rejects" 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.
