  1. Unit Two Assessment Bacteria, Protists, Fungi, and Plants

  2. 1. What protists uses a pseudopod to move and capture food? An Amoeba

  3. 2. What does the name streptococcus tell you about the bacteria? The shape of the bacteria is spherical or round.

  4. 3. How are bacteria unlike plant and animal cells? Bacteria are prokaryotes, which means that there is not a membrane around the nucleus in a bacterium cell. These cells are smaller and microscopic.

  5. 4. What is the benefit of nitrogen-fixing bacteria? Nitrogen-fixing bacteria converts nitrogen in the air and soil so that plants can use it.

  6. 5. What is a prokaryotic cell? A prokaryotic cell does not have a membrane around its nucleus. These cells are smaller and microscopic.

  7. 6. What are cilia? Cilia are bristle-like structures on some protists that help them move.

  8. 7. What is the purpose of endospores? Endospores are thick-walled structures around bacteria that protect bacteria and make it difficult to treat with antibiotics or vaccines.

  9. 8. What is an antibiotic? An antibiotic is medicine produced by one organism and kills another organism such as bacteria.

  10. 9. How are bacteria helpful? Medicines Nitrogen-fixing bacteria Saprophytes Help clean up oil spills and other pollution

  11. 10. How are protists classified? Plant-like Animal-like Fungus-like

  12. 11. What do the terms aerobes and anaerobes mean? Aerobes- organisms that use oxygen for respiration Anaerobes- organisms that do not use oxygen for respiration

  13. 12. What are saprophytes? An organism that uses dead material as a food and energy source. Bacteria is a saprophyte.

  14. 13. How are saprophytes helpful to the environment? Saprophytes control environmental pollution by breaking down dead and decaying material.

  15. 14. Protists are grouped according to what criteria? Shared characteristics – plant-like, animal-like, and fungus-like

  16. 15. What are spiral-shaped bacteria called? Spirilli-spirillum

  17. 16. What is a pathogen? A pathogen is an organism that causes a disease.

  18. 17. What are sphere-shaped bacteria called? Cocci - coccus

  19. 18. What are organisms that use oxygen for respiration called? Aerobes

  20. 19. What is a vaccine? A vaccine is a solution made from dead or damaged bacteria that is used to prevent bacterial diseases.

  21. 20. How do bacteria reproduce? Binary fission

  22. 21. What are rod-shaped bacteria called? Bacilli - bacillum

  23. 22. What is flagellum and what is its purpose? Flagellum is a long, whip-like structure on some protists that help them move.

  24. 23. What are toxins? Toxins are poisons produced by pathogens.

  25. 24. What are organism that can live without oxygen called? anaerobes

  26. 25. What are nitrogen-fixing bacteria called? Nitrogen-fixing bacteria

  27. 26. What are endospores? Thick-walled structures around bacteria

  28. 27. What are organisms that use dead material for food and energy sources? saprophytes

  29. 28. What are bacteria? Bacteria are one-celled organisms without membrane-bound cells(nucleus).

  30. 29. What is fission? Fission is the way all bacteria reproduce.

  31. 30. Where are Archaebacteria found? Archaebacteria are found in extreme environments such as Great Salt Lake, Dead Sea, ocean vents, geysers, and swamps.

  32. 31. What are examples of food that were produced with the help of bacteria? Cheese, yogurt, sauerkraut

  33. 32. What kills harmful bacteria? Vaccines and antibiotics

  34. 33. What are the characteristics of fungi? Eukaryotic Heterotrophic Multicellular Decomposer Can be parasitic

  35. 34. What are examples of vascular plants? Trees Angiosperms- flowering plants Ferns Horsetails and Club Moss

  36. 35. What are the general characteristics of plants? Can make their own food – autotrophic Have a cell wall Multicellular Eukaryotic cell

  37. 36. What causes ringworm and athlete's foot in humans? Fungus

  38. 37. Yeast, molds, and mushrooms are classified in what kingdom? Fungus

  39. 38. What is the purpose of a dichotomous key? To identify an unknown organism

  40. 39. How many choices are used at each step in a dichotomous key? There are two choices.

  41. 40. What is binomial nomenclature? The two-part naming system used to name organisms.

  42. 41. In a scientific name, which name is the genus and which one is the species? The genus is the first part of the name; the species is the second part of the name. The genus is always capitalized.

  43. 42. Who developed the current system for classifying organisms? Linnaeus

  44. 43. What organisms reproduce by fission? Bacteria – Eubacteria and Archaebacteria

  45. 44. What is a eukaryotic cell? A eukaryotic cell has a membrane around the nucleus and other organelles.

  46. Review you vocabulary words. • Anaerobe • Aerobe • Antibiotics • Endospores • Nitrogen-fixing bacteria • Saprophytes • Pathogens • Prokaryotic • eukaryotic • Cilia • Flagella • Algae • Protozoan • Amoebas • Nonvascular • Vascular • Angiosperms • Genus • Species • Binomial nomenclature
