|---|
| prokaryote | DNA is scattered in the cell |
| eukaryote | contains a true nucleus |
| Archaebacteria | bacteria that live in extreme environments |
| autotroph | can produce its own food |
| heterotroph | feeds off other organisms |
| capsule | structure on a bacteria that protects it from WBC |
| flagella | long, whiplike hair |
| DNA | genetic information |
| cell wall | just inside the capsule |
| endospore | formed when the bacteria faces unfavorable conditions |
| penicillin | antibiotic that puts holes in the cell wall |
| anaerobe | can grow without oxygen |
| aerobe | needs oxygen to grow |
| binary fission | organism splits into 2 equal parts |
| conjugation | form of sexual reproduction |
| asexual reproduction | only 1 set of DNA is used |
| sexual reproduction | 2 sets of DNA used, offspring look different from parent |
| cilia | short hairs used for movement |
| unicellular | made of only 1 cell |
| multicelllular | made of more than 1 cell |
| colonial | when unicellular organisms live together in close association |
| contractile vacuole | pumps water out of a paramecium |
| diatoms | are used to make toothpastes and other cleaning products |
| nonmotile | cannot move |
| depression slide | needed when viewing a protist |
| warm temperatures, darkness, water, and food | conditions necessary for bacterial growth |
| air, water, or organisms they infect | means which bacteria can be transmitted |
