| A | B |
|---|
| Protein Coat | Protects the virus hereditary material |
| Capsule | Outer coating on most bacteria |
| Vaccine | Weakened or dead viruses |
| Antibiotic | Chemical produced by bacteria |
| Bacteria | Bad: causes food poisoning, produces toxins, damages leather, and breaks down asphalt; Good: some are decomposers and break down pollutants |
| Host | A living organism that provides a source of energy for a virus |
| Endospore | Protects the hereditary material of bacteria |
| Bacteriophage | Bacteria eater; attacks E. Coli Bacterium |
| Flagellum | Whip-like structure that many baceria use to aid in movement |
| Virus | Tiny particles containing hereditary material; can only reproduce with help of living cells; causes colds, herpes, fever blisters, and AIDS; |
| Moneran | Unicellular, no nucleus, cell wall, capsule (some), flagella (some); mostly heterotrophs |
| Why are viruses not living organisms? | They are not cells, they don't perform complex chemical activities (eat, ingest, excrete), don't grow, can't reproduce on own |
| Binary Fission | Cell division; parent cell divides into two identical sister cells; asexual reproduction |
| Conjugation | Partial exchange of DNA material between some unicellular organisms |
| Toxin | Poison produced by some bacteria that causes diseases |
| Infectious Diseases | Illnesses that pass from one organism to another |
| Decomposer | Organisms that break down large chemicals into small chemicals in dead organisms |
| Asexual Reproduction | Reproductive process involving only one parent; binary fission |
| Sexual Reproduction | Reproduction process involving two parents that combine genetic material to produce a new organism; conjugation |
| Parasite | Organisms that live on or in a host and causes harm to the host; most viruses |
