The Cell Wheel

THE CELL WHEELIE!

I.  Make two circles from a heavy paper provided. The circles should each have a diameter of 29 cm.

II.  For the bottom wheel, divide the circle in half. Divide each half into 20 equal segments. (For a total of 40 segments on entire circle) On one half of the circle, list each of the 20 cell organelles. On the corresponding segment of the other half, list the function of each organelle. Make sure you indicate on an organelle if it is only found in a plant or animal cell. For those only found in plant cells, shade those slices green. For those only found in animal cells, shade those slices pink. (If the organelle is found in both, you do not need to shade it)

III.  For the top wheel, make two opposite windows (cut out slices) the width of one segment of your bottom wheel. You will need to make the slices about 13.5cm long. Just make sure you don’t cut the slices too close to the center of the wheel!

IV.  On your top wheel, you need a drawing of a cell or cell organelles. You may glue your original homework drawings on the wheel, or you may print cell organelles/cells from the computer and glue those.

V.  Place the top wheel on the bottom wheel and fasten through the center so the top wheel rotates. Now you have your “cell wheelie”!

VI.  Make sure that when an organelle appears in one window (slit), its correct function should appear in the opposite window (slit).

Use the following organelles for your cell wheelie:

1. Nucleus 11. Vacuole

2. Ribosome 12. Chloroplast

3. Rough Endoplasmic Reticulum 13. Mitochondria

4. Smooth Endoplasmic Reticulum 14. Nucleolus

5. Cytoskeleton (Microtubules/Microfilaments) 15. Cilia

6. Golgi Apparatus 16. Flagella

7. Lysosome 17. Centriole

8. Peroxisome 18. Cytoplasm

9. Cell Wall 19. Cell Junctions

10. Plasma Membrane 20. Chromatin/Chromosomes
