| Ligand | general term for any type of molecule that a receptor binds to |
| Lysosomes | digestive organelles filled with toxic chemicals and degradative enzymes |
| Mitochondria | cytoplasmic compartment of eukaryotic cells used for energy production |
| Nuclei | cytoplasmic campartments of eukaryotic cells that are the defining characteristic of a eukaryote |
| Phagocytes | one group of wbc's that travel to all parts of the body to clean up any problems--move by amoeboid motion--crawl along to find unwanted material |
