LEARNING OBJECTIVES
These lecture learning objectives are a study guide based on the VMC Prokaryotic Cell Lecture PowerPoint Show:
- 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.
- 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
The Prokaryotic Cell Lecture materials include:
- learning objectives
- PowerPoint lecture
- homework
- additional readings
- practice test & review questions
- photos of bacterial colonies & bacteria viewed with microscope

LECTURE POWERPOINT
Versions of Prokaryotic Cell PPT:
- Student's Prokaryotic Cell PowerPoint Show
- Student's Prokaryotic Cell PowerPoint PDF Printout
Printing: The best way to print out the PowerPoint Show is to download the PDF version. Select Print, and, when the Print screen comes up, go to Print Handling options. Under Page Scaling, select "Multiple pages per sheet", Under Pages per sheet, select "2". That uses up less paper, placing two slides on each page.
PROKARYOTIC CELL HOMEWORK ASSIGNMENTS
These assignment will help you understand osmosis, introduced in this lecture, and prokaryotic cell structure and function. Check with instructor to see if this homework is assigned.
