  1. TAXONOMY, BACTERIA AND VIRUSES REVIEW

  2. The science of grouping and naming organisms is called TAXONOMY

  3. A step by step way to identify an organism using a series of paired descriptions Dichotomous key

  4. The taxon for animals that are warm blooded, have body hair, and produce milk for their young. Mammalia

  5. What is the naming system called that gives each organism a two word scientific name?Turdusmigratorius“American Robin” Binomial nomenclature

  6. Which scientific name is written correctly? FelisConcolor Felisconcolor Felisconcolor FelisConcolor

  7. The names of the taxons from the most general to the most specific. Kingdom, phylum, class, order, family, genus, species.

  8. What level of classification is smaller than an order but larger than a genus? • Family

  9. What is this diagram called? • Cladogram

  10. Name the derived characteristic for the amphibians? • Four limbs

  11. Which organisms are the most closely related? • Primates, Rodents and Rabbits

  12. Which organisms are the most closely related? Mountain Lion and Domestic Dog

  13. What are the names of the three domains? • Archaea • Bacteria • Eukarya

  14. Which two domains contain only unicellular, prokaryotic organisms? • Archaea • Bacteria

  15. Organisms that make their own food. Autotrophs

  16. Organisms that must consume food. Heterotrophs

  17. Which kingdom contains organisms that are multicellular, eukaryotic, and autotrophs? Plantae

  18. Which kingdom contains organisms that are prokaryotes, unicellular, and live in extreme environments? Archaebacteria

  19. Which kingdom contains organisms that are prokaryotes, unicellular, and may decompose dead matter? Eubacteria

  20. Which kingdom contains organisms that are eukaryotes, unicellular or multicellular, mobile and heterotrophs? Protista

  21. Which kingdom contains organisms that are multicellular eukaryotes, mobile and heterotrophs? They do not have cell walls. Animalia

  22. Which kingdom contains organisms that are multicellular eukaryotes, have cell walls with chitin, and absorb their food? Examples are yeast, mold, and mildew. Fungi

  23. A nonliving parasite • Virus

  24. The outer protein coat of a virus • Capsid

  25. A virus that infects a bacteria • Bacteriophage

  26. What do viruses need to reproduce? • A living cell as a host

  27. What type of viral infection is shown in the diagram? • Lytic infection

  28. Lysogenic cycle • A virus cycle where a virus injects its DNA into a cell, reproduces normally, but does not cause the cell to lyse.

  29. Are viruses alive?? Explain. • NO • Viruses do not have all the characteristics of living things. • Not made of cells • Cannot live independently. • Must infect a living cell to reproduce.

  30. How do viruses cause disease? • By disrupting the cell’s equilibrium.

  31. Identify the three shapes of bacteria Bacillus – rod shaped Spirillum – spiral shaped Coccus - round

  32. What is the term for a disease causing organism? Pathogen

  33. How do bacteria reproduce? • Binary Fission – Asexual Reproduction

  34. What is the name of the process where two bacteria exchange part of their DNA to increase diversity? Conjugation

  35. Name two ways bacteria are beneficial. • Decomposeers • Nitrogen fixation • Used to produce food. • Digest food in the digestive tract. • Synthesize drugs such as insulin. • Cleanup oil spills.

  36. Name two diseases caused by bacteria • Tetanus • Strep throat • Tuberculosis • Bacterial Meningitis • Lyme disease

  37. Name two viruses that cause disease. • Influenza • HIV virus causes AIDS

  38. What body system is affected by AIDS? What type of cells are infected by the HIV virus? Immune system Helper T Cells

  39. What can you do to treat or prevent a viral disease? • Vaccines can prevent a viral disease. • Antibiotics do not work on viral diseases.
