About this Document

This is a list of questions that I think are useful. If you can answer all you should have a fairly good grasp on the lecture content (which is the material that will be on the first test).

MICR 3050 Test 1 Study Guide Chapter 1 1. Understand the basics about microorganisms: what they are, and what their significance is. 2. Know the differences and similarities between prokaryotic cells and eukaryotic cells. 3. Know the basics about acellular infectious agents (viruses, viroids, satellites, and prions). 4. Understand how to read a phylogenetic tree: what is the significance of thedistance between organisms? 5. Are archaeons more similar to eukaryotes than bacteria? 6. What are the general characteristics of archaeons?What about bacteria? What distinguishes the two from each other? 7. What are the two main organelles that bacteria have? (think: energy production)How does endosymbiotic theoryexplain the emergence of these organelles? 8. What are some examples of eukaryotes? What is special about protists? 9. Why is the fossil record sparse for microbes? Know the basic trends in the microbial timeline. 10. What is the driving force behind the evolution of microbes?What are some methods used? 11. Know the difference between a species and a strain. 12. Know the scientists involved with the discovery of microbesand the disproving of the theory of spontaneous generation. 13. Also know the scientists involved with the development of the germ theory of disease. 14. What are Koch’s postulates? What are they used for?What materials do you need to use them? 15. Also know the scientists involved with the furthering of microbiology studies inthe lecture slides (names, general contribution to the field of science) Chapter 2 1. Understand the basics of how light-bending is used to make a light microscope work. 2. Understand terms like resolution, working distance, aperture, and refractive index. 3. What is the difference between the bright-field and the dark-field microscopes? What are they best suited for? 4. Why is staining useful? What does fixation have to do with staining? 5. What are the types of stains and their uses? 6. What is the difference between simple and differential staining? 7. Know how Gram staining works (know the color of the cells at each step as well as the microscopic reasons behind why it works). 8. What is the importance of acid-fast staining? 9. What specific structures are often targeted for staining? Chapter 3 1. Know all the names of bacterial shapes and arrangements. 2. Understand the importance of the surface-to-volume ratio. Do cells want it to be higher or lower, and why? 3. What is the plasma membrane made out of? How does polarity play a role in the structure of a membrane? 4. Are saturated fats more liquid or more solid? What about unsaturated fats? 5. What functions do membrane proteins do and what are thetwo types (think: location in the membrane)? 6. What is the cell wall made out of? How does it strengthen the cell’s survivability? 7. What are peptidoglycans? Describe the alternating mesh that peptidoglycans form. Why is lysozyme important to peptidoglycans?What do interbridge linkages do? Is this a selectively permeable barrier like the plasma membrane? 8. Understand the differences between gram-positive and gram-negative cell walls. 9. What is LPS and what is its significance to gram-negative cells? What are its three parts? There is a whole list of why LPS is important; how much of this list do you know? 10. What makes an outer membrane permeable? 11. Understand how osmotic pressure can affect a cell (shriveling or lysing). How does having a cell wall help against osmotic pressure? 12. What are the basic facts about capsules and slime layers? How do they help bacteria survive? Chapter 7 1. Know the differences between culture media types and how to classify them (defined vs. complex, liquid vs semisolid vs solid, supportive vs enriched vs selectivevs differential). It is helpful to know some ofthe complex media components. 2. Know some examples of the different types of culture media. Note that some media types can fit more than one classification. 3. What is a pure culture? 4. What is streak plating? What the end goal? 5. What is a spread plate; how is it made? What about apour plate? What is the acceptable numerical range for counting bacteria on a plate? 6. Understand dilution and what effect it has on the total count of the microbes. 7. Understand how to describe a colony (form, elevation, margin).
