Download 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.
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
2. Ribosome
3. Rough Endoplasmic Reticulum
4. Smooth Endoplasmic Reticulum
5. Cytoskeleton (Microtubules/Microfilaments)
6. Golgi Apparatus
7. Lysosome
8. Peroxisome
9. Cell Wall
10. Plasma Membrane

11. Vacuole
12. Chloroplast
13. Mitochondria
14. Nucleolus
15. Cilia
16. Flagella
17. Centriole
18. Cytoplasm
19. Cell Junctions
20. Chromatin/Chromosomes
Helpful hints: 9 degrees on protractor is perfect size for windows (360 divided
by 40 sections). Don't color plant parts such a dark green and animal parts
such a dark pink that you cannot see what you've written. Use pencil so you can
erase if you tend to be messy. Write about the part structures and functions
in words that make sense to you (not always the book's definition), and
concisely enough that they fit in the spaces provided. The nucleus here is a cell
part, NOT the center of an atom...
