Cell City
Floating around in the cytoplasm are small structures called organelles. Like the organs in your own body, each one
carries out a specific function necessary for the cell to survive. Imagine the cell as a miniature city. The organelles might
represent companies, places or parts of the city because they each have specific jobs. Below are the descriptions of the
important parts of the Cell City.
A. City Limits – Controls what goes in and out of the city.
B. Road System – Sends messages and materials from one part of the city to another, within the Municipality.
C. City Hall – Controls all the activities of the city.
D. Municipality – The area within the City Limits where all parts of city are located and residents move about
under the control of City Hall.
E. City Planning Office – The office in City Hall that stores the plans for the construction and operation of the city.
F. Parts Factory – Makes all of the various pieces a city needs, from building supplies to road equipment and more.
G. Warehouse – Stores materials needed by the city.
H. Solar Power Plant – Captures and transforms the sun’s energy into a form the Power Company can use.
I.
Walls – In ancient times, the City Limits were surrounded by walls for protection.
J. Infrastructure – The wiring, plumbing and steel girders that hold up buildings and support the Municipality,
allowing the city to grow over time.
K. Power Company – Releases energy for the city from either imported materials (like fossil fuels) or internally
produced energy sources (Solar Power Plant).
L. Recycling Center – Old and broken items are turned back into raw materials for later use by the Parts Factory.
M. Global Packing and Shipping – Sends messages and materials beyond the City Limits.
As you move through this worksheet, see if you can match the important parts of the city listed above to the specific
organelles found in cells. Be sure to write neatly, and in complete sentences.

4. The mitochondria are tiny bean-shaped structures in the cytoplasm with a smooth outer membrane, and a
greatly folded inner membrane. They supply the energy for the cell by transforming sugars into energy.
