I. INTRODUCTION Independent Study Questions 1.) What is the fundamental difference between eukaryotic and prokaryotic cells? Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex). 2.) List and describe the two domains of prokaryotic organisms. a. Bacteria- Most are a specific shape (cylindrical‚ spiral‚ or spherical). Cell

My topic that I found interesting that relates to microbiology is Biological Warfare. It is where organisms such as bacteria‚ viruses‚ fungi‚ toxins are used to kill or injure people. Organisms that are used in biological warfare are called agents. Biological agents have been around since ancient times. Archers would infect their arrows by dipping them in dead‚ decomposing bodies or blood that is mixed with feces. Now in modern times‚ biological warfare has become more sophisticated. In WW1‚
