2. NUCLEUS Found in Eukaryotic cells Holds cells ______
(hereditary information)

3. Ribosome Makes proteins (chains of many bound amino acids)
Line is protein strand
Red balls are 2 ribosome subunits

4. Endoplasmic Reticulum (ER)
Rough ER
Attached __________
Helps to transport ________
Smooth ER
Lacks __________
Also helps transport proteins
Makes lipids
Breaks down toxic substances
Interesting – some drugs and alcohol cause increase in the number of smooth ER  this increases a persons tolerance to the drug.

5. Golgi Apparatus Packaging and distribution center
_________ from ER are modified
Then repackaged for use somewhere else inside or outside cell

6. Mitochondrion
Takes energy from organic compounds (things with carbon like glucose) to make ATP
What types of animal cells will have the most Mitochondria?

7. ATP Adenosine Tri-phosphate
The molecule that provides energy for cellular processes.
Energy released when a bond is broken.
Like a rechargeable battery!

8. Chloroplast – plants only!
Photosynthesis
Take light energy to make carbohydrates (glucose)
Carbohydrates now available to make ______.

9. Other plant organelles
Cell wall
Supports and protects cell
Helps cell connect to neighboring cells
Central Vacuole
Most of cell volume taken up by this organelle
Stores water mostly
When full, it presses the cytoplasm against the cell wall
Why might this be important for a plant?

10. Cell Membrane Lipid Bilayer
Regulates what enters and leaves the cell
Many _______ are found within the membrane that help things pass through
Helps maintain HOMEOSTASIS (Chemical Balance)
