7. Cell Organelles © J Beauchemin 2006
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. What are Cell Organelles?
Organelle= “little organ”
Found only inside eukaryotic cells
All the stuff in between the organelles is cytosol
Everything in a cell except the nucleus is 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.”

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

10. What is the 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.

11. What is the 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.

12. What is the 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.

13. That looks familiar…what is a polypeptide?
What is the 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.
That looks familiar…what is a polypeptide?

14. What is the 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.

15. Which organelles do lysosomes work with?
What are the Lysosomes?
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?

16. What is the 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.

17. What is the Chloroplast?
Found only in plant cells
Contains the green pigment chlorophyll
Site of food (glucose) production
Bound by a double membrane
Chloroplasts absorb light, which is the catalyst for photosynthesis.

18. What is the Cell Wall? Found in plant and bacterial cells
Rigid, protective barrier
Located outside of the cell membrane
Made of cellulose (fiber)
This is an actual microscopic image. Explain that the colors are added digitally to enhance the different parts.

19. What type of microscope may have been used to take this picture?
What are the 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?

20. Where else have we talked about microtubules?
What is the Centriole?
Aids in cell division
Usually found only in animal cells
Made of microtubules
Microtubules are also part of the cytoskeleton.
Where else have we talked about microtubules?

21. Do it again pg. 92
What is the function of the Ribosome?

22. Pg. 92 Out
What is the function of the Vacuoles?

23. In Pg. 94
What is photosynthesis the process of?

24. Do it Now Pg. 94
What is Cellular Respiration the process of?

You will not write answers on the white paper
You will write answers on the Poster paper
You will do a gallery walk around the room to put information in your flip book
This will be timed and you will move as groups
