Difficulty: EasyPrinciples of Classification and Binomial Nomenclature

Match each taxonomic concept or scientific naming convention on the left with its corresponding rule or definition on the right.

  • Genus nameFirst part of a scientific name; always begins with a capital letter
  • Specific epithetSecond part of a scientific name; always begins with a lower-case letter
  • KingdomHigh taxonomic rank grouping related phyla or divisions
  • Binomial nomenclatureThe formal two-word system of naming species using Latinized terms

Answer

Genus name matches with 'First part of a scientific name; always begins with a capital letter'; Specific epithet matches with 'Second part of a scientific name; always begins with a lower-case letter'; Kingdom matches with 'High taxonomic rank grouping related phyla or divisions'; Binomial nomenclature matches with 'The formal two-word system of naming species using Latinized terms'.
Each taxonomic component correctly pairs with its rule: Genus is capitalized and comes first; Specific epithet is lower-case and comes second; Kingdom is a major taxonomic rank above Phylum; Binomial nomenclature is the overall two-name scientific system.

Step-by-Step Solution

1
Identify the standard rule for writing the genus name in binomial nomenclature.
The genus name is the first word in a binomial pair and is capitalized.
According to international rules of botanical and zoological nomenclature, generic names must start with an upper-case letter.
2
Identify the rule for writing the specific epithet.
The specific epithet is the second word and starts with a lower-case letter.
The species identifier distinguishes individual species within a genus and is always lower-case.
3
Determine the structural role of a Kingdom in taxonomic hierarchy.
A Kingdom is a broad category grouping related phyla or divisions.
Hierarchy proceeds from broad categories down to specific ones: Kingdom, Phylum, Class, Order, Family, Genus, Species.
4
Define the term binomial nomenclature.
It is the standard two-word scientific naming system introduced by Carl Linnaeus.
The term 'binomial' literally means 'two names'.
