| Exponential growth | Population growth that is unhindered because of the abundance of resources |
| Logistic growth | Population growth that is controlled by limited resources |
| Conjugation | A temporary union of two organisms for the purpose of DNA transfer |
| Plasmid | A small, circular section of extra DNA that confers one or more traits to a bacterium and can be reproduced seperately from the main bacterial genetic code |
| Transformation | The transfer of a DNA segment from a nonfunctional donor cell to that of a functional recipient cell |

| Endosphere | The DNA and other essential parts of a bacterium coated with several hard layers |
| Strains | Organisms from the same species that have markedly different traits |
| F(x) Plasma Membrane | To negotiate what materials pass into and out of the cell |
| F(x) Flagellum | To move the bacteria from place to place |
| F(x) Capsule | To adhere to surfaces as well as to ward off infection-fighting agents |
