| endoplasmic reticulum (ER) | two types (smooth and rough); synthesize some molecules |
| amount of ER fluctuates | depends on cells' activity |
| intracellular highway | direct molecules from one part of cell to another |
| qualities of smooth and rough ER | may be continuous |
| Rough ER | has ribosomes embedded in it; protein synthesis |
| vesicles | sacks where proteins are packaged |
| smooth ER | synthesizes steroids and other lipids; regulates calcium intake; aids in breakdown of toxic substances |
| golgi apparatus | processes, pagkages, and secretes proteins made by rough ER; system of membranes but one membrane |
| function of golgi apparatus | checks and modifies proteins before they are used |
| vacuole | comes out |
| lysosomes | small spheres with a single membrane; found in animals, fungi, and protists, rarely found in plants |
| warriors of the cell | break down proteins, carbs, lipdids, DNA, RNA, old organelles, viruses and bacteria |
