1. DO NOW: Element Molecule Organelle Cell Tissue Organ Organ System
Organism
DO NOW:
Organize the following terms from smallest to largest.
Cell
Organ
Organelle
Molecule
Organ System
Tissue
Organism
Element

2. Let’s Review the Types of cells
bacteria cells
Prokaryote
- no organelles
Eukaryotes
- organelles
animal cells
plant cells

3. Cells & Cell Organelles
Doing Life’s Work

4. Why study cells? Cells  Tissues  Organs  Bodies
bodies are made up of cells
cells do all the work of life!

5. Cell membrane Structure Function double layer of fat
phospholipid bilayer
Includes receptor molecules
Function
separates cell from outside
controls what enters or leaves cell
recognizes signals from other cells
allows communication between cells

6. Cell Wall Structure: Function:
Rigid layer surrounding the cell membrane in plants, algae, fungi, and most bacteria
Function:
Provides support
Protection
Prevents over-expansion of cell

7. Cytoplasm Structure: Function jelly-like fluid
Holds organelles in place
Helps to transport materials

8. Nucleus Structure Function nuclear membrane
Contains: nucleolus and chromosomes (DNA)
Function
control center of cell
protects DNA

9. Nuclear Envelope Structure: Function: Double lipid bilayer
Surrounds genetic material and nucleolus

10. Nucleolus Structure: Function: Inside nucleus Surrounded by membrane
Ribosome Factory

11. Chromatin Structure: Function: Made up of DNA and proteins
Forms chromosomes within the nucleus of eukaryotic cells

12. Ribosomes Function Structure
Link amino acids together to from proteins
AKA protein factories
read instructions to build proteins from DNA
Structure
some free in cytoplasm
some attached to ER
Ribosomes on ER

13. Endoplasmic Reticulum
Function & Structure:
Rough ER
ribosomes attached
helps produce proteins
Smooth ER
makes lipids for membranes

14. Microtubules Structure: Function: Tube shaped
Made of protein and tubulin
Function:
Responsible for movement within the cell

15. Microfilaments Structure: Function:
Thin, twisted proteins in the cytoplasm of eukaryotes
Function:
Keep organelles in place
Help with cell movement

16. Vacuoles Structure Function: food vacuole Membrane Sac Large in plants
Storage of materials
Moves materials around cell
food vacuole

17. Mitochondria Structure: Function Double Membrane
Supply energy to the cell by converting molecules from food into usable energy

18. Golgi Apparatus Structure Function membrane sacs
finishes, sorts, labels & delivers proteins
like UPS headquarters
shipping & receiving department
ships proteins in vesicles
“UPS trucks”
vesicles
carrying proteins
transport vesicles

19. Chloroplasts Structure: Function: Stacks of disc-shaped sacs
Inner and outer membranes
Function:
Carry out photosynthesis to convert solar energy into energy-rich molecules (sugar)
Helps to grow plant

20. Lysosomes Structure membrane sac of digestive enzymes Function
digest food
used to make energy
clean up & recycle
lysosomes

21. Cilia and Flagella Structure: Function: Slender and hair-like
Ex. Tail on sperm
Function:
Move liquid
Move cell

22. endoplasmic reticulum
nucleus
protein on its way!
DNA
TO:
RNA
vesicle
TO:
TO:
vesicle
ribosomes
TO:
protein
finished protein
Golgi apparatus
Making Proteins

23. Our organelles do all those jobs!
Cell Summary
Cells have 3 main jobs
make energy
need food + O2
cellular respiration & photosynthesis
need to remove wastes
make proteins
need instructions from DNA
need to chain together amino acids & “finish” & “ship” the protein
make more cells
need to copy DNA & divide it up to daughter cells
Our organelles do all those jobs!

24. Selling Cells!
You and your partner will be assigned an organelle and create an advertisement for it
You need to state the function and structure of your organelle as well as creating a slogan for your organelle
Be creative!

25. Example Slogans McDonalds Subway Nike I’m lovin it Eat fresh
Just do it

26. Let’s Practice We will brain storm ideas for the cell membrane
No one can use the cell membrane for their organelle later

27. What is the structure of the Cell Membrane?
Lipid bilayer
What is the function of the Cell Membrane?
Regulates what can go in or out of the cell
What are some possible slogans for this organelle?

28. Selling Cells
You and your partner will BOTH need to create a plan on pg. 20 of your journals that shows most of the criteria on your directions sheet
Once you show me your plan on pg. 20, I will give you the brochure paper to create your actual advertisement
Be creative!
This is due at the end of class.
When you are done, you can get on Achieve 3000
