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 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.

The Cell Mechanic
You are the owner and operator of a very specialized shop-you repair people’s defective cells. Please tell each of the
customers below what part needs to be repaired in their defective cell and what that part does for the cell.
Example: The customer’s cell does not seem to know what to do. It seems to be out of control:
Diagnosis: The cell must have a problem with it’s nucleus, because that is what controls the cell
Customer 1: The customer complains that all his oranges are green, his carrots are white, and none of his trees turn red
or yellow in the fall.
Diagnosis:
Customer 2: This gentleman’s cells keep filling up with amino acids, but never seem to make proteins.
Diagnosis:
Customer 3: When this woman goes out to her garden, all her plants are floppy and sag on the ground even though she
gives them plenty of water, they don’t seem to be able to store the water.
Diagnosis:
Customer 4: This woman’s cell has too much power, they seem to be bursting with way too much energy.
Diagnosis:
Customer 5: This poor man’s animal cells just can’t seem to divide and make more animal cells
Diagnosis:
Customer 6: This woman’s cell has plenty of material to use, but it never seems to get where it is supposed to go.
Diagnosis:
Customer 7: This man’s cells are filling up with broken and damaged parts and the food in the vacuole just seems to sit
in there without being digested.
Diagnosis:
Customer 8: A man discovered his prize cactus plants seemed to be starving to death even though they were in bright
light during the day.
Diagnosis:
Customer 9: This poor woman’s cells keep filling up and bursting, things get in but don’t seem to be able to get out.
Diagnosis:
Customer 10: All the material being produced and transported by the cell ends up remaining simple compounds and are
never combined into more complex ones.
Diagnosis:
