Unit Two Assessment

Bacteria, Protists, Fungi, and Plants


1 what protists uses a pseudopod to move and capture food

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

An Amoeba


2 what does the name streptococcus tell you about the bacteria

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

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

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

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

6. What are cilia?

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


7 what is the purpose of endospores

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

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

9. How are bacteria helpful?

Medicines

Nitrogen-fixing bacteria

Saprophytes

Help clean up oil spills and other pollution


10 how are protists classified

10. How are protists classified?

Plant-like

Animal-like

Fungus-like


11 what do the terms aerobes and anaerobes mean

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

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

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

14. Protists are grouped according to what criteria?

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


15 what are spiral shaped bacteria called

15. What are spiral-shaped bacteria called?

Spirilli-spirillum


16 what is a pathogen

16. What is a pathogen?

A pathogen is an organism that causes a disease.


17 what are sphere shaped bacteria called

17. What are sphere-shaped bacteria called?

Cocci - coccus


18 what are organisms that use oxygen for respiration called

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

Aerobes


19 what is a vaccine

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

20. How do bacteria reproduce?

Binary fission


21 what are rod shaped bacteria called

21. What are rod-shaped bacteria called?

Bacilli - bacillum


22 what is flagellum and what is its purpose

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

23. What are toxins?

Toxins are poisons produced by pathogens.


24 what are organism that can live without oxygen called

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

anaerobes


25 what are nitrogen fixing bacteria called

25. What are nitrogen-fixing bacteria called?

Nitrogen-fixing bacteria


26 what are endospores

26. What are endospores?

Thick-walled structures around bacteria


27 what are organisms that use dead material for food and energy sources

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

saprophytes


28 what are bacteria

28. What are bacteria?

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


29 what is fission

29. What is fission?

Fission is the way all bacteria reproduce.


30 where are archaebacteria found

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

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

Cheese, yogurt, sauerkraut


32 what kills harmful bacteria

32. What kills harmful bacteria?

Vaccines and antibiotics


33 what are the characteristics of fungi

33. What are the characteristics of fungi?

Eukaryotic

Heterotrophic

Multicellular

Decomposer

Can be parasitic


34 what are examples of vascular plants

34. What are examples of vascular plants?

Trees

Angiosperms- flowering plants

Ferns

Horsetails and Club Moss


35 what are the general characteristics of plants

35. What are the general characteristics of plants?

Can make their own food – autotrophic

Have a cell wall

Multicellular

Eukaryotic cell


36 what causes ringworm and athlete s foot in humans

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

Fungus


37 yeast molds and mushrooms are classified in what kingdom

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

Fungus


38 what is the purpose of a dichotomous key

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

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

There are two choices.


40 what is binomial nomenclature

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

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.
