| Golgi Apparatus           | Modifies, sorts, and packages proteins/lipids for transport.                                              | Stack of flattened, membrane-bound sacs (cisternae).                                                   | Eukaryote only                |

| Chloroplast               | Converts light energy to glucose via photosynthesis (in autotrophs).                                      | Oval-shaped with inner stacked membranes (thylakoids) in a fluid stroma; contains chlorophyll.          | Eukaryote only (plant/algae cells) |
| Vacuole                   | Stores water, nutrients, or waste; maintains turgor pressure (in plants).                                 | Large, membrane-bound sac (small in animal cells, very large in plant cells).                          | Eukaryote only (larger in plants) |
| Cell Wall                 | Provides structural support and protection for the cell.                                                  | Rigid, thick layer outside cell membrane (composition varies: cellulose in plants, peptidoglycan in bacteria). | Both (composition differs) |
