| Sexual | the production of offspring by means of mixing genetic material of two parents. |
| Species | The most specific level; organisms that can reproduce and produce fertile offspring. |
| Unicellular | made of only one cell |
| Classification | The process of grouping organisms based on shared characteristics. |
| Genus | A group of closely related species. |
