Summary Introduction
To analyze:
The reason why it is difficult to make generalization about the group of organisms sometimes referred to as ‘microbes’.
Introduction:
Microbes are the smallest organisms on earth. They may be composed of prokaryotic or eukaryotic cells and may be unicellular or multicellular.

With respect to bacteria, define morphological arrangement. Explain thoroughly!
. This flowchart helps distinguish among organisms by asking questions that have one of two
possible answers. As a result, this flowchart can also be called a dichotomous key (from Greek
dikho- 'in two' + temnein 'to cut'). Complete the flowchart by properly placing these genera:
Bacillus, Corynebacterium, Escherichia, Mycobacterium, Neisseria, and Staphylococcus. You
may need to look up additional information about these genera.
