Theory:

The system of naming organisms is known as Nomenclature.
Importance of nomenclature:
Nomenclature is a system that helps people to identify an organism with a standard name anywhere in the world.
The nomenclature system names the organism by a name that contains the genus and species name of the organism. This concept of giving term, which denotes the genus and species of the organism, is known as Binomial nomenclature.
Binomial Nomenclature:
The naming of organisms with two names is known as Binomial nomenclature.
The term was introduced by Gaspard Bauhin in 1623, and was implemented by Carolus Linnaeus in 1753 in his book 'Species Plantarum'. Hence Carolus Linnaeus was known as the father of Modern taxonomy.
Binomial nomenclature is a universal system of naming organisms. According to this system, the name consists of two parts:
  • a generic - starts with a capital letter
  • a specific epithet - starts with a small letter
Example:
The nomenclature for mango is Mangifera indica
Genus name is Mangifera
Species name is indica
Example:
More names:
Thoothuvalai: Solanum trilobatum
Kuppaimeni: Acalypha indica
Onion: Allium sativum
The local name, which is familiar for a particular place, is known as a vernacular name.
The binomial name is a universal name that never changes. The classification and binomial nomenclature of organisms help the scientists to identify any organisms and place them at a particular hierarchy.
