| An inference is derived from | facts or premises |
| The nucleus controls the functions | of a living cell |

| Cytoplasm is a jelly-like substance | that contains the organelles |
| Mitochondria are organelles | that change glucose into usable energy |
| Chlorplasts make | glucose |
| Ribosomes make | protein |
| The Endoplasmic Reticulum | act as a transport system |

| Vacuoles store | starch or water |
| The nuclear membrane protects the | contents of the nucleus. |
| The nucleolus makes | ribosomes |
| Nuclear pores are | openings in the nuclear membrane |
| DNA is stored in | chromatin |
