Question

cell city
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
2. ribosomes
3. nucleus town hall
4. endoplasmic reticulum
5. golgi apparatus postal office
6. protein
7. cell membrane fence
8. lysosomes scrap yard
9. nucleolus

Explanation:

1. Mitochondria are the power - houses of the cell. The hydraulic dam powers the widget shops and carts, so it is like mitochondria.
2. Ribosomes are sites of protein synthesis. Small shops produce widgets, similar to ribosomes making proteins.
3. The nucleus contains genetic information and controls cell activities. Town hall has widget - making instructions and controls widget production, like a nucleus.
4. The endoplasmic reticulum is involved in protein and lipid transport. Special carts transport widgets, similar to the ER's transport function.
5. The Golgi apparatus modifies, packages, and sorts proteins. The postal office packages and labels widgets for export, like the Golgi apparatus.
6. Proteins are the products of the cell's functions. Widgets are the main products of the city, like proteins in the cell.
7. The cell membrane controls what enters and leaves the cell. The fence controls who can enter and leave the city, like the cell membrane.
8. Lysosomes break down waste. The scrap yard breaks down "rejects", like lysosomes.
9. The nucleolus makes ribosomes. The carpenter's union builds the small shops (where widgets are made, like ribosomes make proteins), so it can be compared to the nucleolus.

Answer:

1. Hydraulic dam
2. Small shops
3. Town hall
4. Special carts
5. Postal office
6. Widget
7. Fence
8. Scrap yard
9. Carpenter's union
