| Question | Answer |
|---|---|
| Name the rules for Binomial Nomenclature | Rules--The first letter of the genus name is always capital and the rest are lower case, when printed it is italicized, when hand written it should be underlined. |
| List the Taxonomy Groups | Domain-broadest Kingdom Phylum Class Order Family Genus Species-most specific |
| Name the three domains and kingdoms with them | The three domains are Bacteria, Archaea, and Eukarya. The six kingdoms are Bacteria, Archaea, Protists, Fungi, Plantae, and Animalia. Eubacteria are prokaryotes whose cell walls contain peptidoglycan. |
| Explain the difference between bacteria and archaea | Eubacteria-Very strong cell walls, Contain peptidoglycan, some have a second cell wall. They can live mostly anywhere except extreme environments. Archaebacteria live in three different environments which are 1. Thermoacidophiles live in hot, acidi |
| Shapes and names of bacteria | 1. Spherical=Cocci 2. Rod-shaped=Bacilli 3. Spiral-shape=Spirochetes |
| Know the three extremophiles | Thermoacidophiles live in hot, acidic environments Halophiles live in very salty environments Methanogens cannot live in the presence of oxygen. |
| Bacterial survival individually and population | The endospore helps them survive extreme heat, extreme cold, dehydration, and large amounts of ultraviolet radiation. On a population level they survive on mutations. This leads to new gene combinations, new characteristics, and genetic diversity. |
| Three ways bacteria are beneficial | Nutrient cycling and nitrogen fixation. Bacteria are decomposers, returning vital nutrients to the environment. Nitrogen-fixing bacteria live in a symbiotic relationship in the root nodules of plants such as soybeans, clover, and alfalfa |
| Three reasons viruses are not living | Viruses is a nucleic acid surrounded by a protein coat, do not have cells, and are not considered to be living things. |
| How protist are classified, why might that change, and the three groups of protist | All protists are eukaryotes Some reproduce asexually by mitosis while others exchange genetic material during mitosis. Classified by the way they obtain their nutrients Protozoans are heterotrophs and usually ingest bacteria, algae, or other protozoans |
