How Does a Cell Function Like a City? Think About the Sites and Sounds of a City. You

How does a cell function like a city? Think about the sites and sounds of a city. You see people and cars moving about, buildings, restaurants, and lights everywhere. What a flurry of activity!

Cells, the basic units of life, can be compared to a city. Cells are building and breaking down material. Cells release energy from foods, and then use that energy to make needed cell parts. Cells function to make your body operate like a well run city.

1. Research each cell organelle to determine its function. Write the function down in the space provided below. Below you will find a list of the cell organelles and city analogies. Remember; be creative when making your cell city. Your city can be modern, futuristic, historic, or fantasy, as long as your analogies are similar to those provided below. BE CREATIVE! THINK OUTSIDE THE BOX! Customize the “City Analogies” to fit your city!

City Analogies for a basic modern city Cell Organelles Organelle Functions (make adjustments for your city) Cell Membrane River surrounding the city Cell Wall City Wall or Border of Protection Remember: Includes cytosol plus everything in the cell except the nucleus so Cytoplasm it’s technically already apart of your drawing! Endoplasmic Reticulum Highway or road system Ribosomes Lumber or brick yard/ factory Golgi Bodies (Golgi Apparatus) Post Office or UPS Chloroplasts Solar Energy Plants Nuclear Membrane City Hall Fence with security guard Mitochondria Energy Plants City Hall (or some other central controlling Nucleus body of your city) DNA Original Blueprints of the city RNA Copies of Blueprints Nucleolus Copy Machine Lysosomes Waste Disposal/ Recyclers Warehouses, water towers or garbage Vacuole dumps Protoplasm/ Cytosol Air and Lawns Chromosomes Rolled up blueprints Proteins Lumber or bricks

2. Make a rough draft blueprint of your cell city. It should include labels for all cell organelles and their corresponding city structure. Structures should be labeled Cell Organelle / Analogy Name. Example: Nucleus / City Hall. Give your cell city a name at the top center of your drawing. 3. Make a poster model of your cell city with materials from home. Be sure to label all cell organelles and corresponding city structures. Your model should look like your blueprint but neater and in color. All work that has been finalized and approved MUST be laminated! Please make sure the proper heading including your name date and class period are on the back top right corners of all of your work BEFORE it is laminated!

4. Chose one of the following careers and complete the job associated with that role. Remember, all work that has been finalized and approved MUST be laminated!

Although this activity seems simple, cells are very complex. You will be able to better understand the interrelationship of the cell's organelles through this comparison to a city. This introduction to cells will prepare you for more detailed instruction in the future.
