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?

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? 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? bacteria?

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? bacteria?

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? bacteria?

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? bacteria?

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? bacteria?

Medicines

Nitrogen-fixing bacteria

Saprophytes

Help clean up oil spills and other pollution


10 how are protists classified
10. How are protists classified? bacteria?

Plant-like

Animal-like

Fungus-like


11 what do the terms aerobes and anaerobes mean
11. What do the terms aerobes and anaerobes mean? bacteria?

Aerobes- organisms that use oxygen for respiration

Anaerobes- organisms that do not use oxygen for respiration


12 what are saprophytes
12. What are saprophytes? bacteria?

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? bacteria?

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? bacteria?

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


15 what are spiral shaped bacteria called
15. What are spiral-shaped bacteria called? bacteria?

Spirilli-spirillum


16 what is a pathogen
16. What is a pathogen? bacteria?

A pathogen is an organism that causes a disease.




19 what is a vaccine
19. What is a vaccine? called?

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? called?

Binary fission


21 what are rod shaped bacteria called
21. What are rod-shaped bacteria called? called?

Bacilli - bacillum


22 what is flagellum and what is its purpose
22. What is flagellum and what is its purpose? called?

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


23 what are toxins
23. What are toxins? called?

Toxins are poisons produced by pathogens.



25 what are nitrogen fixing bacteria called
25. What are nitrogen-fixing bacteria called? called?

Nitrogen-fixing bacteria


26 what are endospores
26. What are endospores? called?

Thick-walled structures around bacteria



28 what are bacteria
28. What are bacteria? energy sources?

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


29 what is fission
29. What is fission? energy sources?

Fission is the way all bacteria reproduce.


30 where are archaebacteria found
30. Where are Archaebacteria found? energy sources?

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? help of bacteria?

Vaccines and antibiotics


33 what are the characteristics of fungi
33. What are the characteristics of fungi? help of bacteria?

Eukaryotic

Heterotrophic

Multicellular

Decomposer

Can be parasitic


34 what are examples of vascular plants
34. What are examples of vascular plants? help of bacteria?

Trees

Angiosperms- flowering plants

Ferns

Horsetails and Club Moss


35 what are the general characteristics of plants
35. help of bacteria?What are the general characteristics of plants?

Can make their own food – autotrophic

Have a cell wall

Multicellular

Eukaryotic cell




38 what is the purpose of a dichotomous key
38. What is the purpose of a dichotomous key? kingdom?

To identify an unknown organism



40 what is binomial nomenclature
40. What is binomial nomenclature? key?

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.



43 what organisms reproduce by fission
43. What organisms reproduce by fission? organisms?

Bacteria – Eubacteria and Archaebacteria


44 what is a eukaryotic cell
44. What is a eukaryotic cell? organisms?

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