Study Guide

/ NAME:______
Microbiology BI234
Do to past cheating on study guides these guides MUST be written and
will not be accepted as a typed document.

What types of eukaryotes are studied in microbiology?

Describe the endosymbiotic theory of the origin of mitochondria and eukaryotic cells.
List evidence that supports the endosymbiotic theory.
What types of eukaryotes have flagella or cilla?
What is the difference between a prokaryotic and eukaryotic flagella? /
How do cilia differ from flagella in both structure and function? /
Describe the glycocalyx of eukaryotes.
Cell Structure / Found in Prokaryotes and/or Eukaryotes / Function / Structure / Location in Cell
Cell Wall
Cell Membrane
Nucleus
Endoplasmic Reticulum
Golgi Apparatus
Mitochondria
Ribosomes
Using figure 4.2 as a guide draw a eukaryotic cell and label all of the cell structures listed above. To understand microbial-host interactions you must know the cell structures of both microbe and the host!!
DO NOT COPY and PASTE from INTERNET…that doesn’t teach you anythingJ
What are the two basic types of microscopic fungi?
How is a yeast cell distinguished?
What are hyphae?
What is mycoses?
How are fungi used in industry?
Fungi are heterotrophic. What does this mean?
Describe how a fungus invades its host.
What do colonies of yeast look like in culture?
What is mycelium. Describe its appearance.
What are septa? Describe the internal cell structure of a nonseptate hyphae.
What is the purpose of a fungal spore?
Compare the differences between asexual and sexual spores.
What is the difference between sporangiospores and conidiospores.
Why do you think fungi have evolved to have both asexual and sexual spores?
Why do we classify protozoans together?
Describe the location and function of the ectoplasm and endoplasm.
What do parasitic protozoa live on in their host?
What is a protozoa’s main limiting factor?
What is a protozoa doing during the trophozoite phase?
What is a protozoa cyst, who does it form, and what is its purpose?
What dictates the mode of transmission of a protozoa? Explain this using the examples Trichomonas vaginalis and Giardia lamblia.
What is conjunction in protozoa?
What organisms make up helminthes?
Describe a flatworm. How are flatworms subdivide? Describe each of the subdivided groups.
What are the more developed and less developed organ systems in helminthes? Why do you think this is so?
What is the difference between an intermediate, definitive, and transport host?
What is usually the source and routes of infection for helminthes?
Using the pinworm as an example draw and describe a helminth life cycle.
Describe how malaria is contracted and occurs in the body.
***Understanding of the underlined terms in this document is needed to succeed in this class. To further study these terms do one of the following:
Make flash cards of all terms
Make a concept map of all terms (if you don’t know what this is look it up on Wikipedia)
Write out definitions of all terms
Or come up with your own way of studying these terms. Just make sure to ok it with me to make sure you’ll get your extra credit.
This must be turned in attached to this study guide at the time the study guide is due!!!!
What’s working well and what’s a suggestion to help things work better?
