Chapter 10

Chapter 10 deals with bacteria and viruses. Specifically, the chapter describes classifying bacteria, bacterial reproduction, the shapes of bacteria, Kingdom Eubacteria, Kingdom Archaebacteria, how bacteria are good for people and the environment, how bacteria are harmful, classifying viruses, and multiplication of viruses. We also discussed terms not introduced in Chapter 10 that are important to our study of bacteria and viruses.
