Name: Period: Date: Cell City Analogy 2012 A cell is very much like a city because, like a city, each cell has a purpose and components that are needed by other cells or communities. In this activity, you will read the Cell City Analogy, and identify the cell parts that are similar to the underlined parts of the city story (use page 12-18). In a far away city called Cell City, the main export and production product is the steel bolt. Everyone in the town has something to do with steel bolt making and the entire town is designed to build and export bolts. The town hall library has the instructions for bolt making. Bolts come in many shapes and the citizens of Cell City can get the instructions and begin making their own bolts, although the instructions can’t leave the library. A Photocopy Center makes it possible to copy the instructions if you want to create another Sister Cell City. Bolts are generally produced in small shops around the city. After the bolts are constructed, they are placed on special carts which can deliver the bolts anywhere in the city. These carts are transported on roads that connect the entire city together. In order for a bolt to be exported, the carts take the bolts to the postal office, where they are packaged and labeled for export. Sometimes bolts don't turn out right, and the "rejects" are sent to the scrap yard/recycling center where they are broken down for parts or destroyed altogether. The town powers the bolt shops and carts from a hydraulic dam that is the city’s power station. A large wooden fence encloses the entire city, and only the postal trucks (and citizens with proper passports) are allowed outside the city. The city is held together by bridges and buildings that give the city its shape. The city itself has nice fresh air flowing in and around the streets and buildings. Match the parts of the city (underlined) with the parts of the cell. Cell Part Cell Membrane Function Encloses the cell and acts like a gatekeeper regulating what goes in and out.
