Cell Analogy Introduction: An analogy compares two different things to better explain one. You will create analogies to better explain how the parts of the cell work together to help the cell survive. The organelles of the cell work together for the cell to do all of its daily jobs. For example, the nucleus tells the cell membrane what materials are needed; the cell membrane lets them in; these materials may go to the ribosomes where they are used to make proteins and are then are finished by the endoplasmic reticulum and packaged by the Golgi body to be sent where they are needed in the cell. The Task: In this project, you get to be creative. You and your partner will work together to draw a poster that describes a cell as though it were some place people would go to such as an amusement park (like Disneyland or Elitch’s), museum, library, store, school or other similar places. Chose parts of that place that do the same or similar jobs as the parts of the cell. Describe the parts of the cell as the things one will see in this place. It is most important that your analogies (comparisons) make sense and relate to the real structure and job of the cell organelle you are describing. An example would be if I describe the cell as a factory, I might describe the membrane as a security fence with. You will be graded on your creativity as well as correct descriptions and comparisions. Your poster must include: 1. Written descriptions and pictures. 2. Descriptive analogies of the organelles. Include the cell membrane, ribosomes, endoplasmic reticulum, Golgi body, nucleus, vacuole, lysosome and mitochondria. Each organelle’s job must be included in your description. 3. For your comparisons, use the following format: The cell membrane is like ______ because the cell membrane does ______ and the _______ does __________. 4. Your drawing must be one large picture, not many small separate pictures. 5. Both authors and the parts they did (this is how I will give you your grade.) Grade 1. Correct descriptions of organelles and their jobs with the job of the object is it compared to: 15 points 2. Organelles are compared to objects that actually do similar jobs: 15 points 3. Design – poster is neat and colorful: 5 points 4. Creativity: 5 points 5. Complete sentences: 5 points TOTAL: 45 points 5 4 Describes all organelles in analogies and most of the compared objects. 3 2 1 Missing either some organelle descriptions or some compared job descriptions. Missing some organelle descriptions and several comparisons. Missing many descriptions. Description (15 points) Describes jobs of all organelles and their compared objects in analogies. Analogies (15 points) Analogies are all relevant and clearly explained in the correct format. Analogies are all relevant and almost all are explained in the correct format. Almost all analogies are relvant and a few should be explained more clearly or in the correct format. Several analogies aren't relevant and most need to be explained more clearly. Analogies aren't relevant and aren't explained clearly. Creativity (5 points) Unique comparisons, Creative ideas Creative ideas, some unique comparisons Creative ideas Some creative ideas Only used ideas provided in class. Design (5 points) Poster is neat, colorful and artistic. Poster is neat, and artistic. Poster is neat, and somewhat artistic. Poster is somewhat neat. Poster is messy. Grammar (5 points) Uses complete sentences Mostly uses complete sentences Few complete sentences Incomplete sentences. Incomplete sentences make it difficult to read. You will receive a grade for the part you did. You must do HALF of the project, you should not finish your partner’s half of the project even if they aren’t here to do it.
