10. Turn, Pair, Share

11. Create a Venn Diagram
Eukaryotic
Prokaryotic

12. Create a Venn Diagram Eukaryotic Prokaryotic
Nucleus and nuclear membrane
DNA = linear chromosome
Most are multicellular
Bigger than P
Contains Golgi body, mitochondria, ER, other membrane enclosed organelles
Prokaryotic
Nucleoid region (no true nucleus or membrane)
DNA = circular chromosome
Most are unicellular
Smaller than E
Lacks most of the organelles in Eukaryotic Cells
Cytoplasm, cell wall (plants), DNA, cell membrane, ribosomes,
Obtain energy from sunlight or chemicals in environment

13. Microscopes!

Always carry a microscope with one hand holding the arm and one hand under the base.
Base

15. Fill in the table on your worksheet.
What’s my power?
To calculate the power of magnification, multiply the power of the ocular lens by the power of the objective.
What are the powers of magnification for each of the objectives we have on our microscopes?
Fill in the table on your worksheet.

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

17. Let’s give it a try ...
1 – Turn on the microscope and then rotate the nosepiece to click the red-banded objective into place.
2 – Place a slide on the stage and secure it using the stage clips. Use the coarse adjustment knob (large knob) to get it the image into view and then use the fine adjustment knob (small knob) to make it clearer.
3 – Once you have the image in view, rotate the nosepiece to view it under different powers.
Be careful with the largest objective! Sometimes there is not enough room and you will not be able to use it!
4 – When you are done, turn off the microscope and put up the slides you used.

18. You do not need to use the stage clips when viewing wet-mount slides!
How to make a wet-mount slide …
1 – Get a clean slide and coverslip from your teacher.
2 – Place ONE drop of water in the middle of the slide. Don’t use too much or the water will run off the edge and make a mess!
3 – Place the edge of the cover slip on one side of the water drop.
4 - Slowly lower the cover slip on top of the drop.
Cover Slip
Lower slowly
You do not need to use the stage clips when viewing wet-mount slides!
5 – Place the slide on the stage and view it first with the red-banded objective. Once you see the image, you can rotate the nosepiece to view the slide with the different objectives.

19. MICROSCOPE STATIONS Today and tomorrow  tomorrow we
will compare animal vs. plant cells!

20. Organelles Review
Mr. W Organelles Song

21. Virtual Lab
Worksheet

22. Skeletal Muscle Cell Structure and Function
Multinucleated because they consist of several cells that have fused together.
Contain many mitochondria because they require a lot of energy
Contain the protein
filaments (myosin
and actin) which are
responsible for the
muscle contraction.

23. White Blood Cell Structure and Function
A normal lymphocyte has a large, dark-staining nucleus with little to no cytoplasm
if you think of the cytoplasm as a factory then what the cell needs to produce decides how big the factory/cytoplasm needs to be
The ribosomes are involved
in protein synthesis 
generate large quantities
of cytokines and
immunoglobulins

24. Pancreatic Cell Structure and Function
These exocrine cells show a strongly basophilic cytoplasm that represents the area occupied by the rough endoplasmic reticulum. The apical side of the cells is filled with zymogen granules that contain a variety of digestive enzymes  duodenum

25. Enzymes Review
