|---|
| cytoplasm | region inside the cell membrane containing a gel-like material |
| ribosomes | chemical factories where proteins are produced |
| flagellum | long, whiplike structure that extends from the cell membrane and passes out through the cell wall |
| asexual reproduction | a reproductive process that involves only one parent and produces offspring that are identical to the part |
| binary fission | process in which one cell divides to form two identical cells |
| sexual reproduction | involves two parents who combine their genetic material to produce a new organism, which differs from both parents |
| conjugation | one bacterium transfers some of its genetic material into another bacterial cell through a thin, threadlike bridge that joins the two cells |
| respiration | process of breaking down food to release its energy |
| endospore | small, rounded, thick-walled, resting cell that forms inside a bacteria cell |
| decomposers | organisms that break down large chemicals in dead organisms into small chemicals |
| niche | role or job of the organism in its environment |
| prokaryote | cells that do not have an organized nucleus to contain the DNA |
| bacteria cell shapes | spherical, rodlike, spiral |
| cell wall | rigid protective wall surrounding most bacteria cells |
| cell membrane | inside the cell wall, controls what goes in and out of the cell |
| cytoplasm | inside region of the cell containing the organelles and a gel-like material |
| genetic material | contains the instructions for the cell's functions |
| Anton Van Leeuwenhoek | discovered bacteria clees |
| Archaebacteria Kingdom | most primitive, many live in extreme environments |
| Eubacteria Kingdom | do not live in extreme environments, found everywhere else, most are harmless |
| Legume Plants | soy beans, peanuts, peas, alfalfa that contain eubacteria in the nodules on their roots that convert nitrogen for the plant to use |
| Bacteria help us | digest food, make insulin, make vitamins, flavor fook, prevent harmful bacteria from attaching to intestines |
| Antibiotic | can be used to kill bacteria, but cannot kill viruses |
