| Mitochondria | Powerhouse of the cell. |
| Where is ATP produced? | Mitochondria |
| Ribosomes | Site of Protein Synthesis |
| Smooth ER | builds lipids, breaks down glycogen |
| Rough ER | Makes proteins, has ribosomes. |
| ER | Helps maintain Homeostasis |
| Cytoskeleton | Microfilaments, intermediate filaments, microtubles. |
| How does the Cytoskeleton move? | Cilia and Flagella. |
| Vesicles | Lysosomes, peroxisomes, Protein synthesis. |
| Golgi Apparatus | Modify, concentrate and package proteins. |
| How are vesicles transported to the plasma membrane and discharged? | Golgi Apparatus |
| Plasma Membrane | Acts as a barrier and covers the surface of the cell, allows cell to excrete waste. |
| Basic Parts of Cells: | Nucleus, Cytoplasm, and Plasma Membrane. |
| What has a phospholipid bilayer? | Plasma Membrane. |
| What makes up 90% of the cell? | Central Vacuole |
| What does the central vacuole store? | water, enzymes, toxins |
| What makes a plant stand up? | If the central vacuole is filled with water. |
| What two plastids exist? | Chloroplasts and Chromoplasts. |
| What are chloroplasts? | Thykaloids. Light+Energy=Carbs |
| What are chromoplasts? | Colorful pigments. May or may not be involved in photosynthesis. |
