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 similar jobs. Below are the descriptions of important parts of Cell City. Organelle Name Building, Factory, or Business in the City City Border Patrol-­‐ Controls what goes in and out of the city Train yard and tracks – Provides space for the production of important materials for cell city maintenance and transports them to where they need to go in the city. Construction Company – produces materials for building structures in the city and repairing broken structures. Enables all of the businesses in the city to carryout their jobs with the materials produced by the Construction Company. Use the trains to get around. City Hall -­‐ Controls all the major activities of the city. Hazardous Waste Center – Where toxic chemicals are stored and broken down Packaging/Mailing Centers-­‐ Adds the finishing touches to products and then ships them to their destinations Recycling Centers/Garbage Trucks – Recycles used materials and transports waste out of the city Warehouse -­‐ Stores extra materials needed by the city Power Company -­‐ Produces energy for the city by “burning” fuel Solar Power Plant – Uses the sun’s energy to produce power for the city Streets – Connect all of the different parts of the city within the city limits As you move through this worksheet, see if you can match the important parts of the city listed on the first page of this packet to the specific organelles found in cells. Be sure to write neatly, and in complete sentences. 1. The nucleus is a large, round/oval structure usually located near the center of the cell. It is the control center for all the activities of the cell. a) What company or place does the nucleus resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 2. The cell membrane is a thin, flexible envelope that surrounds the cell. It allows the cell to change shape and controls what goes into and out of the cell. a) What company or place does the cell membrane resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 3. The Rough Endoplasmic Reticulum consists of a network of tube-­‐like passageways. Ribosomes attached to the membrane of the Rough ER produce proteins. The Rough ER then sends the proteins to where they need to go in the cell so that the cell can carry out its life functions. a) What company or place does the Rough Endoplasmic Reticulum resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 4.

It helps organelles and materials move throughout the cell. a) What company or place does the cytoplasm resemble in a Cell City? ________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 5. The mitochondria are 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. a) What company or place do the mitochondria resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 6. The Smooth Endoplasmic Reticulum helps the cell breakdown toxic chemicals. a) What company or place does the Smooth ER resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 7. The chloroplasts are oval, green structures found in the cytoplasm of plant cells. They capture the sun’s energy and use it to produce sugars in a process called photosynthesis. a) What company or place does the chloroplast resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 8. The lysosomes are small round structures found in the cytoplasm. They contain digestive enzymes that break down large food particles or dead organelles into simple substances that can be used again by the cell. They also transport waste outside of the cell. a) What company or place do the lysosomes resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 9. Proteins are one of the most important molecules in the cell. They make up cell parts and enable the cell to carryout virtually all of its functions. They are produced by Ribosomes. a) What company or place do the Proteins and Ribosomes resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 10. The vacuole is a large, round sac found in the cytoplasm. It stores water, food, waste, and other materials needed by the cell. a) What company or place does the vacuole resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 11. The Golgi body consist of flattened sacs of membrane that surround materials, identify them, and bring them to where they need to go in the form of smaller membrane sacs called vesicles. a) What company or place does the Golgi body and vesicles resemble in a Cell City? _________________________________________________________________________________________________________________________ b) Why do you think so? _________________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________________ 12. There are 3 organelles missing from the list above. What are the organelles? What jobs would these organelles carry out in cell city? _________________________________________________________________________________________________________________________

_________________________________________________________________________________________________________________________ Your name: _________________________________________________ The Great Organelle Debate! Group members: ____________________________________________________________________________________________________ Your organelle: _____________________________________________________ Task For homework last night, you wrote a paragraph about why a particular organelle is the most important organelle in the cell. In this mini-­‐project, you and your team must formulate an argument about why your organelle is the best organelle in the Eukaryotic Cell. You will also be allowed to “bash” other organelles, as long as their arguments are factual and not personal. If you make personal attacks, points will be taken off. Work together to gather as much information as you can and form a persuasive argument that explains why your organelle is the best in the cell! The debate will be held on Friday November 30. Debate Format Round 1: Each group presents their argument on why their organelle is the best in the cell. Opening statements should last no more than 2 minutes. If you are a scribe, then you should take notes on what the presenting group is saying for use in Round 2. Short Break [5 minutes] – groups work together to incorporate any incorrect information given by another group into their approach for Round 2 Round 2: Each group is allowed to “bash” other organelles. The “bashing” must be factual and not personal, if you make it personal, I will take points off. Groups may also point out incorrect information given by another group. We will allow 2 minutes for this. Short Break [5 minutes] – groups should discuss how best to defend themselves against the arguments leveled against them in Round 2 Round 3: Each group responds to the accusations brought against them in Round 2 and ends with a closing argument. The closing statement should also take no more than 2 minutes. * The WINNER will be chosen by a vote at the end of the debate. You may not vote for your own group. In the even of a tie, I will make the final decision. * To Turn in on Friday November 30: 1. Homework paragraph on organelle (1 per person) 2. Opening statement used in Round 1 (1 per group) 3. Closing statement used in Round 2 (1 per group) 4.
