Description
Classification of bacteria and archaea is complex and based on size, shape, and biochemistry (phenotypic classification) or genetics (phylogenetic classification). Size and shape variations range from round to short rods to spirals. Short rods dominate most soil populations. Some soil bacteria are pleomorphic in that they can change size and shape, usually as a function of age. With a light microscope, it is difficult to see anything other than the basic shape of the cells. Figure 3-7 shows a view of Clostridium perfringens
