CELL LAB HOW DID YOU DO??? I love cheek cells!!
Magnification
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?
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
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
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
Your animal cells (cheek cells) should have looked like this:
Based on the picture of the cheek cells, please identify the following structure: Cytoplasm Cell membrane Nucleus Cell wall A Table
The other parts you should have labeled are as follows cytoplasm Cell Membrane
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
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
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
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
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
Can you name the cell type at the tip of the pointer? Tooth Cell I want the tooth! You can’t handle the tooth!
Mushroom cells are different because they are in a different KINGDOM…
Mycelium is a part of the mushroom
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
The difference in size between the bacteria and other cells is similar to the comparison in the drawing below… BACTERIA PLANT CELLS
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
The following picture depicts what type of cell? Bacteria Plant Animal 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

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
