2. Mitochondria  Transfers energy to ATP which powers most of the cell’s reactions  “Powerhouse” of the cell

3. Ribosomes  The site where proteins are made  Found of the rough E.R.

4. Endoplasmic Reticulum  Prepares proteins for export and synthesizes steroids

5.  Rough ER makes proteins in ribosomes, they leave in vesicles and go to the Golgi apparatus

6. The Cytoskeleton  The system of microscopic protein fibers that supports the shape of a cell  Function in cell structure and movement

7. Golgi Apparatus  Processes and packages substances produced by the cell

8. Lysosome  A vesicle that digests molecules & old organelles

9. Chloroplast  Enables plants to make carbs from carbon dioxide and water

10. Cilia and Flagella  Hairlike structures that enable cell movement or move substances across a cell’s surface

11. Examples: CiliaFlagella  Respiratory tract  Bacteria cell

12. Features unique to plant cells  Cell walls  Plastids  Central vacuoles

13. Central Vacuole  When filled with water; keeps plant cells rigid Also stores waste, enzymes, pigments, toxins etc.

14. Plastids-contain their own DNA  Include chloroplasts, chromoplasts, and leucoplasts
