| Virus | an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host. |
| Host | A host cell is a living cell in which a virus reproduces. A primary host or definitive host is a host in which the parasite reaches maturity and, if possible, reproduces sexually. |
| Parasite | an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense. |
| Bacteriophage | a virus that parasites a bacterium by infecting it and reproducing inside it. |

| Bacteria | A member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease. |
| Flagellum | A long, whip like structure that helps a cell to move. |
| Binary Fission | The process by which one cell divides to form two identical cells. |
| Asexual Reproduction | A reproductive process that involves only one parent and produces offspring identical to he parent. |
| Sexual Reproduction | Reproduction in which two parents combine their genetic material to produce a new organism, which differs from both parents. |
| Conjugation | The process in which one bacterium transfers some genetic material to another bacterium through a threadlike bridge. |
| Endospore | A small, Rounded, thick-walled, resting cell hat forms inside a bacteria cell. |
