1. CELL LAB
HOW DID YOU DO???
I love cheek cells!!

2. Magnification

3. Comparing Powers of Magnification
We can see better details with higher the powers of magnification, but we cannot see as much of the image. A B
Which of these images would be viewed at a higher power of magnification?

4. Magnification
To determine your magnification…you just multiply the ocular lens by the objective lens
Objective Lenses have
their magnification
written on them.
Ocular lenses usually magnifies by 10x

5. Magnification on OUR microscope
1. What is the magnification of OUR ocular lens?
2. What is the magnification of OUR low power objective lens?
3. Of our MEDIUM power?
4. Of our HIGH power?
10x 4x
10x
40x

6. Let’s Multiply the FUN!
If you are looking at an object under LOW power, what is the total magnification of the microscope?
Multiply the ocular lens (10x) by the objective lens (4x) to get total magnificiation.
(10x) x (4x) =
40x

7. Your animal cells (cheek cells) should have looked like this:

8. Based on the picture of the cheek cells, please identify the following structure:
Cytoplasm
Cell membrane
Nucleus
Cell wall A
Table

9. The other parts you should have labeled are as follows
cytoplasm
Cell Membrane

10. Based on the picture this is most likely a(n)____:
Animal cell due to the nucleus
A onion cell due to the cytoplasm
A onion cell due to the cell wall
Animal cell due to the chloroplasts
Table

11. I hope you recognized this as an onion cell
I hope you recognized this as an onion cell. Can you think of other ways you could describe this cell?
Plant
Eukaryotic

12. The structure identified by the arrow is the:
Cell wall and nucleus
Cell wall and cell membrane
Cell membrane and cytoplasm
Cell wall and cytoplasm 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

13. Your elodea should have looked like the picture below
Your elodea should have looked like the picture below. As you can see, this cell has a nice green color. What name is given to these green organelles:
C H L O R O P L A S T S

14. Can you think of two other ways you could describe these elodea cells:
PLANT CELLS
E U K A R O Y T I C C E L L S

15. Can you name the cell type at the tip of the pointer?
Tooth Cell
I want the tooth!
You can’t handle the tooth!

16. Mushroom cells are different because they are in a different KINGDOM…

17. Mycelium is a part of the mushroom

18. Unfortunately, many of you may not have been able to locate the bacteria in your field of view. If you were successful, they probably looked like this….. OR

19. The difference in size between the bacteria and other cells is similar to the comparison in the drawing below…
BACTERIA
PLANT CELLS

20. Bacteria are… Complex cells lacking a nucleus and organelles
Prokaryotic cells lacking a nucleus and organelles
Eukaryotic cells containing a nucleus
Prokaryotic cells with a nucleus but no organelles.
Table

24. Which component of the cell theory is represented by the following diagram
All living things are made of cells
Cells are the basic unit of structure and function
All cells come from pre-existing cells
Cells are either eukaryotic or prokaryotic 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28
