Unit Two Assessment

Bacteria, Protists, Fungi, and Plants

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

An Amoeba

2. What does the name streptococcus tell you about the bacteria?

The shape of the bacteria is spherical or round.

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.

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.

5. What is a prokaryotic cell?

A prokaryotic cell does not have a membrane around its nucleus. These cells are smaller and microscopic.

6. What are cilia?

Cilia are bristle-like structures on some protists that help them move.

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.

8. What is an antibiotic?

An antibiotic is medicine produced by one organism and kills another organism such as bacteria.

9. How are bacteria helpful?


Nitrogen-fixing bacteria


Help clean up oil spills and other pollution

10. How are protists classified?




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

12. What are saprophytes?

An organism that uses dead material as a food and energy source. Bacteria is a saprophyte.

13. How are saprophytes helpful to the environment?

Saprophytes control environmental pollution by breaking down dead and decaying material.

14. Protists are grouped according to what criteria?

Shared characteristics – plant-like, animal-like, and fungus-like

15. What are spiral-shaped bacteria called?


16. What is a pathogen?

A pathogen is an organism that causes a disease.

17. What are sphere-shaped bacteria called?

Cocci - coccus

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


19. What is a vaccine?

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

20. How do bacteria reproduce?

Binary fission

21. What are rod-shaped bacteria called?

Bacilli - bacillum

22. What is flagellum and what is its purpose?

Flagellum is a long, whip-like structure on some protists that help them move.

23. What are toxins?

Toxins are poisons produced by pathogens.

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


25. What are nitrogen-fixing bacteria called?

Nitrogen-fixing bacteria

26. What are endospores?

Thick-walled structures around bacteria

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


28. What are bacteria?

Bacteria are one-celled organisms without membrane-bound cells(nucleus).

29. What is fission?

Fission is the way all bacteria reproduce.

30. Where are Archaebacteria found?

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

31. What are examples of food that were produced with the help of bacteria?

Cheese, yogurt, sauerkraut

32. What kills harmful bacteria?

Vaccines and antibiotics

33. What are the characteristics of fungi?





Can be parasitic

34. What are examples of vascular plants?


Angiosperms- flowering plants


Horsetails and Club Moss

35. What are the general characteristics of plants?

Can make their own food – autotrophic

Have a cell wall


Eukaryotic cell

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


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


38. What is the purpose of a dichotomous key?

To identify an unknown organism

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

There are two choices.

40. What is binomial nomenclature?

The two-part naming system used to name organisms.

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.

42. Who developed the current system for classifying organisms?


43. What organisms reproduce by fission?

Bacteria – Eubacteria and Archaebacteria

44. What is a eukaryotic cell?

A eukaryotic cell has a membrane around the nucleus and other organelles.
