Week 3 Discussion: Culturing Microorganisms Required Resources Read/review the following resources for this activity: • Textbook: Chapters 7, 8 • Weekly Concepts Initial Post Instructions Class, let’s discuss the categories that organisms can be grouped in based on their nutritional requirements. Find one microorganism, either a prokaryote or eukaryote, and describe the environment in which it lives. (Does it live underwater? On skin? In soil? Give as many details as possible!) T...
