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. PLANT CELL
ANIMAL CELL

4. Organelles structures in the cell
carry out specific functions in the cell

5. The Parts of the Cell Cells are made up of Different Parts!
Each Part has a Specific Function!
The Parts:
Nucleus
Mitochondria
Cytoplasm
Endoplasmic Reticulum
Ribosomes
Golgi Complex
Vacuoles
Lysosomes
Cell Membrane

6. Cell Membrane
-A protective barrier that encloses a cell. -Separates the cell’s contents from the cells environment. -Cell Membrane is like a Fence.

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

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

10. nuclei and actin filaments in cultured epithelial cells

11. Found INSIDE the Nucleus!
Nucleolus
Found INSIDE the Nucleus!

12. Mitochondria Powerhouse of the Cell
Break down Sugar to Produce all Energy!
In the form of ATP

14. Ribosomes
Protein Factory!
Smallest of ALL organelles

15. Where are Ribosomes?

16. Endoplasmic Reticulum
Carry Proteins and other cell materials from one part of cell to another!
Like Roadways!
Two Types: Smooth and Rough
Rough E.R. has Ribosomes
Smooth E.R. does NOT have Ribosomes!

17. Where are The Smooth and Rough ER?

18. Smooth and Rough ER

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

23. Where Is the Golgi Complex?

24. Vacuoles
The Storage Container
Stores food and water

25. Where are The Vacuoles?
Some Animal Cells have Vacuoles while Others Don’t!!

26. Lysosomes Janitors of the Cell Break down old cell parts!
Release them for recycling

28. Recap: Each Organelle has a Function: Cytoplasm? Nucleus?
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

29. Cell Wall Plant Cell Only!
Rigid, cellulose structure that gives support to a cell.
Although made of different materials algae, fungi, bacteria, and archaea also have cell walls.
Like a wall!

30. Cell Pictures
Cell wall
Cell membrane
Cell membrane

31. Chloroplast Plant Cell Only!! Makes food for the cell.
Chlorophyll traps the sunlight needed to perform photosynthesis and gives plants their green color.
Like a Restaurant!
