Comparing Plant and Animal Cells
Part 1: Anacaris
Question: What organelles can you see in Anacaris?
Materials:
 Anacaris
 Water
 Slide


Microscope
Cover slip




Colored
pencils
Dropper
Rulers
Beaker
Procedure:
1. Clean a slide and cover slip
2. Remove a small leaf from near the tip of an Anacaris plant.
3. Make a wet mount with water of the Anacaris leaf in water
4. Observe the leaf under low power
5. Focus on the leaf carefully, adjusting up and down very slowly
6. Switch to medium power and observe, focusing with the fine adjustment
7. Switch to high power objective and observe, focusing with the fine adjustment.
8. Record observations below on HIGH POWER
Required labels:
Cell wall
Cell membrane
Chloroplast
cytoplasm

Procedure:
1. Remove a very thin piece of onion skin from an onion as demonstrated by the teacher.
2. Place a drop of water on the slide
3. Place the onion in the water
4. Add 1-2 drops of IKI stain.
BE CAREFUL!!! IKI WILL STAIN BOOKS AND CLOTHING
5. Cover with the cover slip
6. Record observation under HIGH POWER!
Collect Data:
Required labels:

Analysis: Write TRUE or FALSE for each statement
1. ____________ Chloroplasts are clearly visible in onion skin
2. ____________ Onion skin is a photosynthetic tissue
3. ____________ The nucleus was visible due to staining of the onion skin.
4. ____________ Onion skin cells have both a cell wall and cell membrane
5. ____________ The cytoplasm is within the cell membrane

Procedure:
1. Carefully clean a slide and coverslip
2. Use a toothpick to gently remove some cheek cells from inside your mouth (teacher will
demonstrate)
3. Roll the toothpick through 1-2 drops of water on the slide
4. Add a drop of methylene blue on a slide
5. Immediately throw out the toothpick
6. Add the cover slip and observe under low, medium, and high powers
7. Record results on HIGH POWER
Collect Data:
Required labels:

_______ X
Analysis: Write TRUE or FALSE for each statement.
1. ___________ Cheek cells are shaped similar to onion cells and Anacaris cells.
2. ___________ Cheek cells have a regular shape.
3. ___________ Cheek cells have a cell wall and a cell membrane.
4. ___________ A nucleus is observed in some cells on high power.
5. ___________ Cheek cells may contain chloroplasts if you just finished eating green vegetables.
6. ___________ Cheek cells have a cell membrane surrounding the cytoplasm.
