Prokaryotic Microbe Lecture Materials

These are the Prokaryotics: Meet the Microbes Lecture materials of the Virtual Microbiology Classroom. The resources below are used to supplement an actual college microbiology course. Anyone taking, teaching or interested in biology may find these materials helpful and is welcome to use them.

The Prokaryotic Microbes lecture materials include:

a list of learning objectives

a PowerPoint lecture

a prokaryote classification homework assignment

practice test questions

review questions

photos of prokaryotes and prokaryotic colonies

links to additional educational resources

PROKARYOTIC MICROBE LECTURE LEARNING OBJECTIVES

These lecture learning objectives are a study guide based on the VMC Prokaryotes: Meet the Microbes Lecture PowerPoint:

Understand the three types of Archaea that we discussed.

Know the three levels of hierarchy in biological classification (out of the nine we discussed) are we mainly going to be referring to in this class.

Understand the difference between Gram-positive and Gram-negative bacterial cell walls.

Know the information presented on the Gram-positive bacterial genera and species that we discussed.

Name and describe the bacterial genera that produce endospores. Are they Gram-positive or Gram-negative?

Which species of bacteria are considered Gram-variable? Why?

What is different about the cell wall structure of acid-fast bacteria when compared to the Gram-positive bacterial cell wall?

How is Blood Agar (BAP) useful in distinguishing between the pathogen Streptococcus pyogenes and normal flora?

Know the information presented on the Gram-negative bacterial genera and species that we discussed.

How is MacConkey's agar useful in identifying different types of Gram-negative bacteria?

Describe the important differences between encapsulated and unencapsulated Haemophilus influenzae.

How is the life cycle of Chlamydia different than that of most bacteria?

PROKARYOTIC MICROBE LECTURE POWERPOINT

All of the lecture PowerPoints used in the Virtual Microbiology Classroom have fill-in-the-blanks on many of the slides to encourage students to pay attention and follow along during the presentation. Instructors, contact us for the information that goes in the blanks.

HELPFUL TIPS: Some of the PowerPoint presentations are large files and may take a few moments to download, depending on the speed of your internet connection. If you are printing a hard copy of the PowerPoint, you can save paper by selecting Handouts (rather than Slides) in the "Print What:" drop down menu of the PPT print screen. Then you can choose the number of slides you want to have on each printed page. If the printed PPT presentation is to be used as student notes, it is best to choose handouts with 2 or 3 slides per page.

PROKARYOTIC MICROBE HOMEWORK

Word document of a bacteria classification spreadsheet for students to construct introduced in previous lecture on Biological Classification. They will build this spreadsheet throughout the semester, as the course introduces them to more types of bacteria.

PROKARYOTIC MICROBE CLASS NOTES

Here are summaries of various subtopics and concepts introduced in this lecture, kind of like really good class notes.

Gram Stain: Differential Stain for Gram+ & Gram- Bacteria Identification

Acid-fast Stain: Identification of Mycobacteria & Nocardia

Endospore Stain: Differentiating Endospores from Vegetative Bacterial Cells

Bacterial Cell Wall Structure

What Is a Bacterial Endospore?

PROKARYOTIC MICROBE PRACTICE TEST QUESTIONS Part I & Part II

Practice test questions designed to help you better understand the material from this lecture. They are based on information in the Prokaryotes: Meet the Microbes PowerPoint Lecture.

PROKARYOTIC MICROBE REVIEW QUESTIONS

Questions designed to help you review the material in the Prokaryotes: Meet the Microbes Lecture.

PROKARYOTIC CELL PHOTOS

The images linked here directly relate to this lecture material and are designed to help student review and study while outside of class.
