Name In this assignment, you will compare cell organelles and functions to those of a working city. Directions 1. Fill in the table to match the parts of a city to the parts of a cell. Explain your reasoning. 2. Draw a diagram of a city. Clip art may be used to add to your city, but it should supplement your drawings (not be entirely done using clip art). 3. Label the city with city AND cell parts! Cell City Introduction Floating around in the cytoplasm are small structures are 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 have similar jobs. Below are the descriptions of important parts of the Cell City: 1. City Limits – Controls what goes in and out of the city. 2. Road System – Allows for movement throughout the city. 3. City Hall – Controls all the activities of the city. 4. City Planning Office – A place in the city hall where plans are made for the construction of the city. 5. Construction Company – Builds structures and buildings for the city. 6. Delivery Van – Delivers products made at the construction company to other locations in the city. 7. Garbage & Recycling Truck – Collects and gets rid of city’s wastes or collects items to be recycled for later use. 8. Shipping Company (Fed-Ex or UPS) – Packages and ships materials throughout the city. 9. Warehouse – Stores materials needed by the city. 10. Power Company – Produces energy for the city. 11. Solar Power Plant – Uses the sun’s energy to produce power for the city. As you read through the following table, see if you can match the important parts of the city listed above to specific organelles found in cells. Be sure to write neatly, and in complete sentences! CELL PART NUCLEUS CELL MEMBRANE ENDOPLASMIC RETICULUM RIBOSOMES NUCLEOLUS GOLGI BODIES FUNCTION 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 thin, flexible envelope that surrounds the cell. It allows the cell to change shape and controls what goes into and out of the cell. Consists of a network of tubelike passageways that proteins from the ribosomes are transported through. Small grain-like bodies made mostly of RNA and produced in the nucleolus. They put together proteins, which are the building-blocks of cell structures. A small, dense object found in the middle of the nucleus. It gives the instructions for making proteins (the building blocks) in the cell. Flattened, sac-like organelles that package and ship materials throughout the cytoplasm and out of the cell. Tiny bean-shaped structures in the cytoplasm with a smooth outer membrane, and a greatly MITOCHONDRIA folded inner membrane. They supply the energy for the cell by transforming sugars into energy. SIMILAR CITY PART REASONING CELL PART CHLOROPLAST LYSOSOMES VACUOLE FUNCTION An oval, green structure found in the cytoplasm. It contains chlorophyll. It captures the sun’s energy and uses it to produce sugars in a process called photosynthesis. Small, round structures found in the cytoplasm. They contain digestive enzymes that break down wastes & large food particles into sugars and other simple substances. A large, round sac found in the cytoplasm. It stores water, food, wastes, or other materials needed by the cell.
