Question: How do plant and animal cells differ?
Hypothesis: If we study a plant cell and an animal cell, then we
will see that they are different from each other because______
_________________________________________________
Materials: light microscope, 2 glass slides, 2 coverslips, dropper,
Methylene Blue, toothpick, onion slice, water
Procedure: Day One---Plant Cell
1. Study the data table.
2. Use the dropper to put a drop of water on the slide.
3. Peel a thin layer of onion and place it as smoothly as you can
in the drop of water.
4. Raise your hand so Mrs. Crumbaker can add a drop of
Methylene Blue.
5. Cover with coverslip. View under low power and then high
power.
6. Locate the cell wall, nucleus, cell membrane and cytoplasm.
Look for chloroplasts. Fill in data table.
7. Draw and label the cell and its parts.
Day Two---Animal Cell
1. Using the dropper, add a drop of water to your slide.
2. Mrs. Crumbaker will give a toothpick to a group member.
That member will gently rub the inside of his/her cheek
with the toothpick and then swirl it in the water drop.
3. Raise your hand so that Mrs. Crumbaker can add a drop of
Methylene Blue.
4. Cover with coverslip. View under low and then high power.
5. Locate the nucleus, cytoplasm and cell membrane. Fill in the
data table.
6. Draw and label the cell and its parts.
