Finding Order in Diversity 18.1
Taxon
• Group or level of organization into which
organisms are classified.
Binomial Nomenclature
• Classification system in which each species is
assigned a two-part scientific name.
Genus
• Group of closely related species, and the first
part of the scientific name in binomial
nomenclature.
Taxonomy
• Discipline of classifying organisms and
assigning each organism a universally
accepted name.
Family
• Group of genera that share many
characteristics.
Order
• Group of
similar
families.
Class
• Group of
similar
orders.
Phylum
• Group of
closely
related
classes.
Kingdom
• Large
taxonomic
group,
consisting
of closely
related
phyla.

  11. 11. Key Concept • How are living things organized for study? –To study the diversity of life, biologists use a classification system to name organisms and group them in a logical manner.
  12. 12. Key Concept • What is Binomial Nomenclature? –Each species is assigned a two-part scientific name.
  13. 13. Key Concept • What is Linnaeus’ system of classification? –Linnaeus’ hierarchical system of classification includes seven levels. They are from smallest to largest species, genus, family, order, class, phylum, and kingdom.
