The chapter reveals the scope of microbiology and gives a broad overview of the areas of science included in this topic. The student will receive an introduction to the history of microbiology, covering the major scientific contributions to the development of microbiology including the development of the microscope and the formation of the germ theory. The student will also be introduced to the hierarchy of classification. The basis of taxonomy is discussed and the order of assigning specific names is clearly presented. Different systems of classification are outlined. There is also a discussion of the origin and evolution of microorganisms that should trigger a good classroom discussion.

Recognizing the structures of the four major types of macromolecules, as well as functional groups, should be emphasized.

The concepts of ions, buffers, and the ph scale always need review and an explanation of the correlation between the ph scale and proton concentration is important.
