Bacteria - one of life's three domains; consists of prokaryotes that are only distantly related to members of the domain Archaea. Binary fission - the process by which a single bacterium divides in half, producing two identical offspring. Conjugation - in prokaryotes, the transfer of DNA from one cell to another via a temporary connection; in single-celled eukaryotes, the mutual exchange of genetic material between two temporarily joined cells. Endospore - a protective resting structure of some rod-shaped bacteria that withstands unfavorable environmental conditions. Flagellum - a long, hair like extension of the plasma membrane; in eukaryotic cells, it contains microtubules arranged in a 9 + 2 pattern. The movement of flagella propels some cells through fluids. Plasmid - a small, circular piece of DNA located in the cytoplasm of many bacteria; normally does not carry genes required for the normal functioning of the bacterium but may carry genes that assist bacterial survival in certain environments, such as a gene for antibiotic resistance. as a gene for antibiotic resistance....
