Prokaryotic Cell Lecture Materials

These are the Prokaryotic Cell Structure & Function 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 Cell Lecture materials include:

a list of learning objectives

a PowerPoint lecture

a homework assignment

"class note" articles

practice test questions

review questions

photos of bacterial colonies and bacteria viewed with microscope

links to additional educational resources

PROKARYOTIC CELL LECTURE LEARNING OBJECTIVES

These lecture learning objectives are a study guide based on the VMC Prokaryotic Cell Structure & Function Lecture PowerPoint:

What is a cell (and what is not)?

Know the two basic types of cells.

Understand diffusion, osmosis, and different types of transport. What are the different ways that molecule can move across the plasma membrane?

Understand the importance of the plasma membrane in regulating the movement of substances into and out of the cell.

Understand osmosis and tonicity (isotonic, hypertonic, hypotonic), and be able to solve a tonicity problem (i.e. If I describe a situation of a specific type of cell sitting in a specific type of solution, be able to tell me which way water would move, into or out of the cell.)

Know the structural parts of a prokaryote and the function of those structures.

Understand the importance of the prokaryotic cell wall. What makes a Gram+ cell different than a Gram- cell; how the differences impact control of microorganisms.

Know the different types of glycocalyces and the advantage that they provide to bacteria that have them.

Know the different types of surface appendages on prokaryotic cells.

Understand the difference between vegetative cells and endospores. What advantage do endospores provide to bacteria?

Know the basic shapes and arrangements of prokaryotic cells.

Understand how the shape of bacterial cells impacts the cell arrangements they occur in.

Know the microbes that we met in this lecture and their relevance to the topics discussed.

- Streptococcus and bacterial slime layer

- Clostridium bacteria and endospres

- Neisseria gonorrhoeae and bacterial fimbriae

PROKARYOTIC CELL 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.

OSMOSIS ESSAY QUESTION HOMEWORK

Word document of a single essay question given to students at the end of lecture. This tool helps the students review their understanding of osmosis (introduced in this lecture) while allowing the instructor to assess the class' understanding of the material.
