|---|
| cell wall | this is the outer most structure of most bacteria cells and all plant cells have this as well |
| living cell | the only place where a virus can multiply |
| AIDS, mumps and colds | these are diseases that are caused by viruses |
| antibiotics | chemicals that can kill bacteria, and aid in the cure of many bacterial diseases |
| prokaryote | bacteria are these because their genetic material in not contained in the nuclei - they do not have nuclei |
| resistant | bacteria are this if they are able to survive in the presence of an antibiotic |
| flagellum | a long, whip-like structure that allows some bacteria to move |
| genetic material | contained in the inner core of a virus |
| bed rest | the most effective treatment for most viral infections |
| pasteurization | the process of heating food to a temperature below boiling point that kills most bacteria |
| vaccine | activates the body's natural defenses |
| non-living | viruses are considered this because they to not show all of the characteristics of life |
| binary fission | the bacterial process of reproduction |
| respiration | the process of breaking down food to release energy |
| obtain food | bacteria that are consumers (heterotrophs) are able to do this by consuming autotrophs and other heterotrophs |
| viruses | these are like parasites because they harm the cells that they enter; there characteristics make them useful in gene therapy because of their ability to enter cells |
| decomposers | these bacteria return basic chemicals to the environment |
| shapes of bacterial cells | spiral, rod shaped and round |
| endospores | these form during harsh environmental conditions |
| Andrew van Leeuwenhook | first discovered bacteria |
| autotrophs | organisms that make their own food |
| asexual reproduction | one cell divides to form two identical cells |
| sexual reproduction | one parent cell exchanges genetic information across a threadlike bridge to another parent cell |
| epidemic | outbreak of a disease in a community |
| symbiosis | a relationship between two organisms where one or both benefit |
