Bacteria/Viruses
| Question | Answer |
|---|---|
| Kingdoms of life that are prokaryotes (lack a nucleus) | Bacteria (Eubacteria and Archaebacteria) |
| Kingdom of bacteria that are your common everyday bacteria. | Eubacteria |
| Kingdom of bacteria that are relatives of the first living organisms (live in extreme environments). | Archaebacteria |
| Type of bacteria that have a spherical shape. | Coccus (cocci) |
| Type of bacteria that have a rod shape. | Bacillus (bacilli) |
| Type of bacteria that have a spiral shape. | Spirillum (Spirilli) |
| Type of Gram stain that results in purple cells (peptidoglycan retains stain); antibiotics usually work against this type of bacteria. | Gram positive (+) |
| Type of Gram stain that results in red/pink cells (peptidoglycan doesn't retain stain b/c of outer membrane protection); antibiotics usually DON'T work against this type of bacteria. | Gram negative (-) |
| Type of bacteria that requires oxygen to survive. | Aerobic |
| Type of bacteria that does NOT require oxygen to survive. | Anaerobic |
| Type of asexual reproduction in bacteria; cells copy DNA and split into 2 new identical cells. | Binary Fission |
| Type of bacterial reproduction which transfers genetic material between bacterial cells using a pilus. | Conjugation |
| Type of bacterial reproduction that transfers fragments of DNA from one cell into another cell. | Transformation |
| Type of bacterial reproduction using a virus. | Transduction |
| Medicine used to kill some types of bacteria. | Antibiotics |
| Bacteria can be _____________, heterotrophs, or decomposers. | autotrophs |
| Are bacteria prokaryotes or eukaryotes? | prokaryotes |
| Are bacteria unicellular or multicelluar? | unicellular, though they may form colonies |
| A disease-causing agent (like some bacteria and viruses). | pathogen |
| 4 ways in which bacteria can be beneficial. | Lives on us/in us, found in nutrient cycles, bioremediation, food fermentation, genetic research |
| Small circular bits of DNA in a bacterial cell. | plasmids |
| Large, free-floating bacterial DNA. | nucleoid |
| Dormant phase for some types of bacteria. Will become active in favorable conditions. | endospore |
| Type of autotroph which uses light energy to produce carbohydrates. | photoautotroph |
| Type of autotroph which uses chemical compounds to produce energy. | chemoautotroph |
