Chapter 11: Characterizing and Classifying Prokaryotes

General Characteristics of Prokaryotic Organisms

2. Identify which two genera of bacteria we associate with the production of endospores. Explain the types of conditions that lead to endospore formation and how the cell benefits from endospore production.

3. Why are endospores difficult to destroy? What is the name of the process of endospore formation? How does the process work? How is it reversed? Explain how endospores are different from fungal spores.

4. Five types of reproduction have been observed in prokaryotes. Which type of reproduction is the most common format? Name and describe all five (descriptions should allow the reader to differentiate the types)Modern Prokaryotic Classification

7. How many total phyla are there for prokaryotes? How many archaeal domains are there? How many bacterial phyla?Survey of Archaea

8. Describe the common features that distinguish archaea from bacteria.

9. Describe the characteristics of following subtypes of archaea: extremophiles, thermophiles, hyperthermophiles, and halophiles.Survey of Bacteria

12. Explain the concept of nitrogen fixation. Explain why nitrogen fixation is important for the earth. Explain the contribution of prokaryotes to this process.

Chapter 12: Characterizing and Classifying Eukaryotes

General Characteristics of Eukaryotic Organisms

14. Looking at the 20 most frequent microbial causes of death listed in the text, how many are caused by eukaryotes? What are two examples of deadly eukaryotic, microbe-caused diseases?

15. “Eukaryotic reproduction is more complicated that prokaryotic reproduction.” Describe four aspects of eukaryotic reproduction that support this statement.

16. Describe what is being divided in the process of nuclear division? What is the difference between a haploid cell and a diploid cell? Why does a diploid organism need to do nuclear division in order to reproduce sexually?

18. Describe the difference between mitosis and meiosis. You should describe differences in the steps of the processes themselves as well as describe number of cells made, if the starting/resulting cells are haploid or diploid, and why the cell would do each process.

21. Describe the major characteristic that most current taxonomists use to classify eukaryotes into kingdoms.Protozoa

22. Describe the four key characteristics that almost all protozoans share.

24. Protozoa can form trophozoites and cysts. What are these structures and how do they contribute to pathogenesis? What bacterial structure is similar in function to a cyst? What conditions can the trophozoite and the cyst survive?

Fungi

28. Describe the two key characteristics of fungi. What is the function of chitin in the fungal cell? What is mycology?

30. Explain what a mycosis is. Approximately haw many fungi can produce mycoses?

Algae

34. Describe the basic characteristics of all algae. What is phycology?

Water Molds

Other Eukaryotes of Microbiological Interest: Parasitic Helminths and Vectors

40. Explain the difference between mechanical and biological vectors.

41. Describe what arachnids are and what they look like. Identify the two key organisms in this category that microbiologists are interested in and explain why microbiologists have an interest.

42. Describe what insects are and what they look like.Identify the five key organisms in this category that microbiologists are interested in and explain why microbiologists have an interest.
