1. The Parts of the Cell

2. The Nucleus
--nuclear envelope
-- chromatin
--nucleolus

3. I am a reticulated python
I am a reticulated python. Ask me what I have to do with the endoplasmic reticulum.
The word “reticulum” means net.

4. Endoplasmic Reticulum - Transport
Figure 4.10

5. Golgi Apparatus - delivery system Cis Face | Trans Face
Cisternae (folds)
Vesicles - package to be delivered

6. Ribosomes - Sites of Protein Synthesis
large subunit
small subunit
Each ribosome has a large and small subunit
Messenger RNA is threaded through the ribosomes
Transfer RNA builds a protein based on the code of the mRNA

7. Lysosomes - Intracellular Digestion Centers
 TAY-SACHS disease – What do lysosomes have to do with this deadly disease?

9. Other Organelles
-- Peroxisomes – result in hydrogen peroxide, broken down by catalase
-- Vacuole -- mainly storage or specific functions (contractile vacuole)
-- Plant cells have a CENTRAL VACUOLE - used for storage and help to maintain hydrostatic pressure

10. Energy Related Organelles
Mitochondria - The Cell's Chemical Furnaces, produces ATP
Chloroplasts - Where Photosynthesis Takes Place
What do these organelles have in common?

11. What happens if your mitochondria don’t work?
Mitochondrial Disease Video
Why is mitochondrial disease so devastating to children?
Consider the mitochondria have their own DNA separate from the parental DNA. How could you cure this disease?

12. Cytoskeleton How do cells maintain their shape? How do they move?
Microfilaments (actin filaments)
Microtubules - form the spindle during cell division
Centrioles – used during cell division to move and separate chromosomes, only found in animal cell
How do they move?
- pseudopod
- cilia
- flagella

13. The Big Picture

14. Mini Quiz 1. What part of the cell produces vesicles for export?
2.  What part of the cell makes proteins?
3.  What part of the cell produces ATP?
4.  What part of the cell transports materials throughout the cytoplasm?
5.  What part of the cell has a cis and a trans face?

16. Can you describe this process in 10 words or less?

18. Show, Don't Tell
Each person will get  a cell concept .   For your concept, design a picture that goes with it and a GESTURE for the idea.  
Be prepared to share your pictures and gestures with the class.   Your classmates will use your picture and your gesture to guess what your concept was. 
It’s like playing a twisted form of charades! You should be able to draw your picture on the fly, on the board, but have a plan in place before you go up there.
