- Recognize the characteristics of life
- Discuss the difference between a virus, viroid, prion, and a living cell.
- Describe the mechanisms of viral infection.
- Describe the distinguishing characteristics of organisms within Bacteria, Archaea, and Eukaryota
- Compare and contrast the variety of organisms within Protista
- Describe the characteristics of the Fungi, Plantae, and Animalia
In this section, the diversity of life is explored with a detailed study of various organisms and a discussion of emerging phylogenetic relationships. This unit moves from viruses to living organisms like bacteria, discusses the organisms formerly grouped as protists, and devotes multiple chapters to plant and animal life.
