| ORGANELLE | Small structures in the cells that carry out specific functions |
| CELL WALL | Found in plant cells. gives support and structure |
| CELL MEMBRANE | Controls what enters and leaves the cell. "SECURITY GUARDS" |
| NUCLEUS | Acts as the BRAIN of the cell. Contains genetic information. |
| MITOCHONDRIA | "POWERHOUSE" of the cell--where energy is produced |
| ENDOPLASMIC RETICULUM | Passageways (HALLWAYS) that carry PROTEINS and other material to the cell. |
| RIBOSOMES | Factories to PRODUCE PROTEINS needed for growth and repair of an organism |
| GOLGI BODIES | Like the MAILROOM of the cell--receive proteins/other materials, PACKAGE them, distribute to cell. |
| CHLOROPLASTS | Found in PLANT cells--contain chlorophyll--where plants make their own food (photosynthesis) |
| VACUOLE | Store food and other materials needed by the cell. Very large in plant cells. |
