1. Cell Organelles!

2. Cell Membrane Also called plasma membrane
Protects and supports the cell
Controls what enters and leaves the cell
Lipid Bilayer (what does this mean??)
Found in all types of cells – prokaryotes and eukaryotes!

3. Cell Wall
Found in eukaryotic plant and protist cells; also in prokaryotes
Adds protection, rigidity, and support
Outside of cell membrane
Made of cellulose (a polysaccharide!)
Allows water and dissolved substances to pass through.

4. The Nucleus Controls most activities in the cell
Contains DNA – the coded instructions for making proteins & other molecules for the cell
The nuclear envelope has nuclear pores, where things can enter or leave
See?

5. Nucleolus Small, dense region in the middle of the nucleus
This is where ribosomes are formed.

6. Cytoplasm Clear fluid within cell that contains all organelles
Moves materials throughout the cell
It’s the light blue/gray stuff in this picture

7. Ribosomes Makes proteins in the cell
May be free in cytoplasm or attached to ER
Proteins are vital to life- all cells must produce them!!!
In prokaryotes and eukaryotes

8. Golgi Apparatus
Stacks of membranes used for storing, modifying, or packaging chemicals
Packaged chemicals can be stored inside the cell or secreted outside the cell
Cells that make saliva or mucus have many Golgi bodies

9. Endoplasmic Reticulum
Series of folded membranes that form sacs or tubes
Rough ER has ribosomes attached

10. Smooth vs. Rough ER Smooth ER Smooth - no ribosomes!
Synthesizes (makes) lipids
Detoxifies drugs
Rough ER
Ribosomes make it look rough or bumpy
Ribosomes synthesize (make) proteins, so the Rough ER is where this happens!

11. Lysosomes Found near Golgi
Contain digestive enzymes to digest unwanted particles
Help white blood cells to destroy bacteria
Clean-up crew!

12. Vacuoles Store food, water, or waste materials
Plant cells have large vacuoles
Vacuoles and lysosomes working together!
Yay teamwork!

13. Chloroplasts Found in eukaryotic plant cells & some protist cells
Chloroplasts capture light energy and convert it into chemical energy during photosynthesis

14. Mitochondria Energy producers – the “powerhouse” of the cell!
Convert chemical energy into useable energy
Many mitochondria in muscle cells – why??
Found in ALL Eukaryotic cells, including plants and animals
Contain DNA from ovum – so all your mitochondria are from your mom!

15. Cytoskeleton
Overlapping network of filaments and fibers that support the cell and help it maintain its shape
Can also help cells move
Microfilaments and microtubules

16. Centrioles are made of microtubules
Centrioles help to make sure cells get organelles they need during cell division
They migrate to either side of the cell and help to pull it apart
Only found in animal cells!
Centrioles are made of microtubules

17. The End
Cells!
