1. Cell Organelles Mr. Nichols PHHS
Use this presentation in conjunction with the Cell Organelle note-taking worksheet. Run through the entire presentation before using it in class so that you know what’s coming next! It helps to print the outline and notes to have with you while presenting so that there are no surprises. –JessB.org

8. Cytoskeleton Acts as skeleton and muscle Provides shape and structure
Helps move organelles around the cell
Made of three types of filaments
Actin, also found in muscle cells, mainly help maintain cell shape in their cytoskeletal role. Microtubules mostly move organelles around the cell. Intermediate filaments also provide structural support.

9. Endoplasmic Reticulum
A.k.a. “ER”
Connected to nuclear membrane
Highway of the cell
Rough ER: studded with ribosomes; it makes proteins
Smooth ER: no ribosomes; it makes lipids
It’s not necessary that the students can read the labels here; just point out the black dots are ribosomes.

10. Ribosome Site of protein synthesis
Found attached to rough ER or floating free in cytosol
Produced in a part of the nucleus called the nucleolus
A polypeptide is a chain of amino acids. In this diagram, you can see the ribosome is making a polypeptide, also known as a protein.

11. Golgi Apparatus Looks like a stack of plates
Stores, modifies and packages proteins
Molecules transported to and from the Golgi by means of vesicles
AKA Golgi Complex. It is not necessary that the students read the labels, this diagram gives them a general idea of the Golgi’s shape.

12. Which organelles do lysosomes work with?
Garbage disposal of the cell
Contain digestive enzymes that break down wastes
Students should recognize the shapes of the Golgi and ER even if they cannot read the captions.
Which organelles do lysosomes work with?

13. Mitochondria “Powerhouse of the cell”
Cellular respiration occurs here to release energy for the cell to use
Bound by a double membrane
Has its own strand of DNA
Explain that this diagram shows the mitochondria cut open to reveal the internal membranes.

14. What type of microscope may have been used to take this picture?
Vacuoles
Large central vacuole usually in plant cells
Many smaller vacuoles in animal cells
Storage container for water, food, enzymes, wastes, pigments, etc.
The image is 2D, so it must have been a light microscope or TEM. If the cell is very tiny, then a TEM was used. Otherwise, a strong light microscope could have captured this image.
What type of microscope may have been used to take this picture?

15. Make it personal
Rank the 5 organelles, (1 being the most) that you think are the MOST important to the cell. Share your rankings with your group mates, be sure to defend any differences that arise.

16. It’s a metaphor…
Create, draw and color a metaphor for the cell and all of the parts we went over (cannot use my city example).

28. -How can you rewrite this conclusion to make it better?
Question of the Day!
My hypothesis was incorrect the nickel did not hold as many drops as I thought; the coin that held the most drops was the quarter. The quarter held on average 22 drops, while the others held less.

41. BREAKING NEWS!!!!
I received an anonymous letter yesterday afternoon from presumably the killer.
The handwriting is consistent with that of Jeff Miller. We have two questions to solve:
1.) Where is the Miller family?
2.) What does the killer want from us?

47. Cell Organelles Organelle= “little organ”
Eukaryotic cells vs. Prokaryotic
The liquid component of the cytoplasm is called cytosol
The stuff in between organelles is called cytoplasm
You may or may not wish to distinguish between cytosol and cytoplasm. The correct use of each term is shown here. Most high school textbooks, however, use the word “cytoplasm” to mean “cytosol.”

48. Cell Membrane Boundary of the cell Made of a phospholipid bilayer
Emphasize word parts here:
phospho= phosphate head; lipid= fatty acid tail
bi= 2

49. Nucleus Control center of the cell Contains DNA
Surrounded by a double membrane
Usually the easiest organelle to see under a microscope
Usually one per cell
Cells with more than one nucleus include muscle cells and liver cells, largely because of the massive volume of cytoplasm and number of organelles that need controlling.

50. Contents of the Safe! 1.) A white mask (pictured on the next slide.)
2.) The minister’s wallet and phone.
3.) A packet of x-rays
4.) A very small journal.

52. X Rays
These x rays are that of “Luke Brave”

53. Journal Entry
In my life I have two regrets. The first that because of the web of lies and deceit that have cost this world two lives.
I killed Kathleen……I killed Luke…I had no choice, the angel of death had instructed me to do I could not refuse….For this I must take myself from this world….Goodbye….
