Cell Structure Lab Answer Sheet
Important Directions for Drawings:
1. Make all drawings in the highest magnification possible.
2. For each specimen, you do not need to fill the circle (field of view) with cells. Just draw
several cells for each.
3. These several cells must be clear drawings. Take your time and draw what you see. Simple
outlines with no detail will not be given full credit.
4. All drawings must be the size that you see them in the field of view. Do not draw them larger
or smaller than they appear in the microscope.
5. Drawings should include the following information:
a. The magnification used while drawing the cell
b. Appropriately labeled cell structures from the following list:
Cell membrane Cell Wall
Chloroplast
Cytoplasm
Vacuole Amyloplast
Nucleus
Chromoplast
A. Cork Cells
1. What cell structures are apparent when looking at cork cells?
2. Why do cork cells appear to be empty?
Cork Cell Drawing Information:
Magnification = ________
Labeled Structures:
B. Onion Cells
3. What did you see through the microscope that appears as a thick line surrounding the cells? (This also
identifies it as a plant and not an animal cell.)
4. What structures can be seen in an unstained onion cell?
5. What differences do you see between the stained and unstained onion cells?
Unstained Onion Drawing Info:
Magnification = ________
Labeled Structures:
Stained Onion Drawing Info:
Magnification = ________
Labeled Structures :
6. Do the onion cells that you examined in this lab have chloroplasts? If chloroplasts are used to capture energy
from the sun, explain why your answer makes sense.
7. Where would you find onion plant cells that have chloroplasts? Explain.
C. Elodea Cells
8. What structures did you see in both Elodea cells and onion cells?
9. What are the differences between Elodea and onion cells?
10. What is the function of a cell wall?
11. How many chloroplasts are in an average Elodea cell? (Count the number in 3 cells and calculate the
average.)
12. How many cell layers were in the Elodea leaf?
Elodea Cell Drawing Information:
Magnification = ________
Labeled Structures:
D. Potato Cell
13. What happened when you put the yellow-colored iodine stain onto the potato?
14. What is the name of the cell organelle that changed color with the iodine? (Hint: starch changes color when
it hits iodine)
Potato Cell Drawing Information:
Magnification = ________
Labeled Structures:
E. Red Pepper Cells
15. How are the red pepper cells different from the Elodea cells?
16. How are the red pepper cells similar to the potato cells?
17. What structure visible in the red pepper cell has not been seen in any other cells during this lab?
Red Pepper Cell Drawing Information:
Magnification = ________
Labeled Structures:
F. Human Cheek Cell
18. What differences do you see between the human cells and the plant cells you have observed?
19. What are the similarities between the human cells and plant cells?
Human Cheek Cell Cell Drawing Information:
Magnification = ________
Labeled Structures:
