1. Discovering the Cell Standard S7L2b:
Relate cells structures (cell membranes, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions

2. Did You Know?
We are made up of microscopic living things called: CELLS
There are Approximately 100 TRILLION cells in the Human Body.
100 Trillion

3. The Parts Cells are made up of Different Parts!
Each Part has a Specific Function!
The Parts:
Nucleus
Mitochondria
Cytoplasm
Endoplasmic Reticulum
Ribosomes
Golgi Bodies (Apparatus)
Vacuoles
Lysosomes
Cell Membrane
Cell Wall
Chloroplast

4. Cell Membrane A protective barrier that encloses a cell.
Regulates what enters and leaves the cell.
Cell Membrane is like a Fence.

5. Cytoplasm Gel-like fluid found all throughout the cell.
Constantly Moving (Swishing around)
All Other Parts are Suspended in Cytoplasm!
Like Jell-O

6. The Nucleus DNA (our genes) Found here! Houses Nucleolus
Directs all of the cell’s activities
tells all the other parts what to do!
Houses Nucleolus
Acts like the Brain!

7. Found INSIDE the Nucleus!
Nucleolus
Found INSIDE the Nucleus!

8. Mitochondria Break down Sugar to Produce all Energy!
In the form of ATP
Power plant of the Cell

9. Where is Mitochondria??

10. Ribosomes Hooks amino acids together to make proteins
All cells need proteins to live
Smallest of ALL organelles

11. Where are Ribosomes?

12. Endoplasmic Reticulum
Site of many chemical reactions
Carry proteins, lipids, and other materials around the cell
Two Types: Smooth and Rough
Like Roadways

13. Where is the:
Rough E.R.?
Smooth E.R?

14. Golgi Bodies: Recieves Proteins (mail) from the E.R.
Packages them (puts it in envelope)
Distributes them to other parts of cell (Mailman)
A.K.A Golgi Apparatus or Golgi Complex
Like Postoffice

15. Where are Golgi Bodies???

16. Vacuoles Stores food and water, In plant cells:
Like a storage container
In plant cells:
Very large
Also act like a lysosome

17. Some Animal Cells have Vacuoles while Others Don’t!!
Where is the Vacuole?
Some Animal Cells have Vacuoles while Others Don’t!!

18. Lysosomes
Contains digestive enzymes, gets rid of waste materials and recycles old cell parts
Janitors of the Cell
Found in animal cells

19. Where are the Lysosomes??

20. Cell Wall The outermost structure of a plant cell. Made of Cellulose
Also found in fungi and prokaryotic cells

21. Chloroplast
Organelle that uses the energy of sunlight to make food (photosynthesis)
Found in plant and algae cells
Make the cells green

22. Recap: Cells are Made of Parts Each Part has a Function: Cytoplasm?
Surrounds and Constantly Moves Organelles
Nucleus?
Brain
Mitochondria?
Powerplant
Endoplasmic Reticulum?
Roadways
Ribosomes?
Protein Factories
Golgi Bodies?
Post Office
Vacuoles?
Food Storage Containers
Lysosomes?
Janitors
