“Cell-O” Project – A model for the eukaryotic animal cell
Mark Shin Cadre 15 EDTC 511
Purpose of this Project: • Make a 3-D model of an animal cell that will help you to visualize an actual animal cell. Supplies & Materials you need: • Jell-O : light-colored (like lemon) or unflavored gelatin • Water, refrigerator, toothpicks, Zip-loc bag (1 gallon) • Various fruits and candies to represent the parts of the cell: (This is a suggestion of materials, so be creative. Choose candies that may do a better job of representing the organelles. o Here are some examples: raisins, gummy worms (plain and sour), gumdrops, gum ball, jelly beans, grapes, mandarin orange sections, cake sprinkles, M&M's, jaw breakers, a small stone fruit (like a plum or an apricot), dried fruit, and/or hard candy. Some suggestions to making the Cell-O: 1. Make the light-colored Jell-O, but make it with a bit less water than the instructions asks for. 2. Place an open plastic bag (1-gallon Zip-Lock bags recommended) inside a sturdy container, like a large bowl or pan. This makes pouring the Jell-O easier. 3. When the Jell-O is almost set (this takes about an hour, but depends on the temperature of your refrigerator), open the bag and start adding the organelles of the cell. 4. CELLO Activity Document Site - This is an online document that is wonderful and gives great directions and sites for making the Cello project. You may want to use the check-off list, but only for the animal cell organelles. 5. Jello Animal Cell – Directions with diagrams, and organelles listed with functions. 6. Making the labels for the organelles: • Print and cut out the organelle labels that you are represented in your Cell-O. • Affix (tape on) the labels onto the toothpicks. Gently insert the tip of the toothpick close to the cell organelle. Organelles – What you will need to have inside your Cell-O: Take a look at The Animal Cell and choose the “Animal Cell” button in this site. It will give you a great start to learning some of the organelles’ functions AND what they look like. • • • • • • • •
Cytoplasm – A great interactive description of cytoplasm. Golgi Apparatus – Functions of the golgi and a nice close up image. Smooth ER – Smooth vs. Rough. Can you tell the difference? Rough ER - Smooth vs. Rough. Can you tell the difference? Mitochondria – A very nice site to learn about Mitochondria! Make sure to click on “Mitochondrion structure” for a nice close up. Nucleus – A great site for learning about the nucleus! Nucleolus – Scroll down to mid-page for functions, and see the image at the top. Ribosome – A great simplified look at Ribosomes! Lysosome – My favorite! There’s a great question about lysosome at the bottom.
