MICROBES

• Microscopic life forms that cannot be seen by the unaided eye

• May be plant or animal

• May be prokaryotic or eukaryotic

Classification Systems

• Taxonomy:– Classification of living organisms into groups

• Phylogenetic Classification System:– Groups reflect genetic similarity and evolutionary

relatedness

• Phenetic Classification System:– Groups do not necessarily reflect genetic similarity

or evolutionary relatedness. Instead, groups are based on convenient, observable characteristics.
