Taxonomy can be described as a system that:
classifies microogranisms, based on their cellular and colonial traits.
classifies microorganisms, based on their genetic makeup.
classifies, names, and identifies microorganisms based on genotypical and phenotypical
characteristics.
classifies microorganisms, based on their phenotypic makeup. - Correct Answer-
classifies, names, and identifies microorganisms based on genotypical and phenotypical
characteristics.
Colonial and microscopic morphologic properties, along with the pigmentation of
colonies, would belong to a microorganism group of __________ characteristics.
phenotypic
subspecies
genotypic
taxonomic - Correct Answer-phenotypic
