1. The three morphological classifications of bacteria are the rods or bacilli, spheres or cocci, and spirochetes. Biologically, bacilli in the gram positives are spore formers, such as Bacillus anthracis (anthrax) and in gram negative are typically enteric species, such as E. coli. Physiological differences could be referring to the oxygen requirements for the various groups. For instance, E. coli and other enteric bacteria are facultative anaerobes. They can use oxygen but do not require it if it's not available. Further, the enteric bacteria typically can ferment lactose as well as glucose. Cocci in the gram positives are well known as the Staphylococcus and Streptococcus genera and are typically normal flora of the skin and can also act ...

Solution Summary

This solution discusses the major bacterial morphologies and how they are related within this group physiologically. Also included is a discussion on the fungal phyla and their reproductive processes. There is also an attached powerpoint with greater detail concerning the fungal groups and their characteristics.
