Imagine trying to talk about one particular plant with someone in another country when each of you knows it only by a different local name — names that change from place to place even within a single country. The conversation quickly becomes confused, because the same organism is being called many different things. Binomial nomenclature is the elegant solution to exactly this problem: it gives every organism one standard scientific name that means the same thing everywhere in the world.
Binomial nomenclature is a system in which every scientific name is made of two parts — the generic name (the genus) and the specific epithet (the species). This two-word system was devised by Carolus Linnaeus and is used by biologists everywhere because it is so convenient. For example, the scientific name of the mango is written as Mangifera indica, where Mangifera is the genus and indica is the specific epithet.
The naming follows a set of universally agreed rules:
- Biological names are generally in Latin and written in italics; whatever their original language, they are treated as Latinised.
- The first word denotes the genus; the second word denotes the specific epithet.
- When handwritten, the two words are underlined separately; in print they appear in italics, showing their Latin origin.
- The genus name begins with a capital letter, while the specific epithet begins with a small letter — as in Mangifera indica.
- The author's name, in abbreviated form, is added at the very end, for instance Mangifera indica Linn., indicating that Linnaeus was the first to describe the species. …
The system of giving every organism a two-part scientific name (genus + species) is called binomial nomenclature, and it was formalised in the mid-18th century. …
Binomial nomenclature (two-word Latinised names) was proposed by Carolus Linnaeus.
Every organism is given a scientific name consisting of two components — a generic name (genus) and a specific epithet (species). This two-name convention is called binomial nomenclature. Carolus (Carl) Linnaeus, the Swedish naturalist, established this practical, standardised system in the 18th century (Species Plantarum, 1753). Charles Darwin proposed …

›Reveal solutionSolution
A binomial scientific name has two parts — the genus name always comes first, followed by the specific epithet.
Carl Linnaeus's binomial system of nomenclature, universally followed today, gives every species a two-word Latinized name:
- The first word is the generic name (genus), e.g. Mangifera in Mangifera indica (mango). It is always written with its first letter capitalized.
- The second word is the specific epithet, e.g. indica, and is always written in lower case. …
- CBSE 2026Set ANNUAL1 markQ.Write True/False: The scientific name of Potato is Solanum Melongena.
›Reveal solutionSolution
This statement is False — potato's correct scientific name is Solanum tuberosum; Solanum melongena is the name of a different plant, Brinjal (eggplant).
According to the binomial nomenclature system (as covered in taxonomy), each species has a unique two-part Latin name consisting of the genus and the specific epithet. Potato belongs to genus Solanum, and its correct species name is tuberosum, giving Solanum tuberosum. Solanum melongena is a different species within the same genus Solanum — it is the scientific name for Brinjal (eggplant), not potato. Both plants belong to the same f …

›Reveal solutionSolution
The two-word (genus + species) naming system devised by Carolus Linnaeus is called binomial nomenclature.
Every known species is given a unique scientific name made up of two components — the genus name followed by the specific epithet. This universal system was proposed by Carolus Linnaeus and is followed internationally under the ICZN (for animals) and ICBN (for plants).

Carl Linnaeus's system of binomial nomenclature gives every species a two-word Latinised name: the first word is the genus (capitalised) and the second is the specific epithet (lower-case), and both are printed in italics (or underlined in handwriting).

›Reveal solutionSolution
Carolus Linnaeus devised binomial nomenclature — a universal two-part naming system for species — making option (b) correct.
Carolus Linnaeus, the 'father of taxonomy', introduced the practice of naming every species with two words: the first denoting the genus and the second the specific epithet, together forming the scientific name of the organism (e.g., Homo sapiens for humans, Mangifera indica for mango). This system is called binomial nomenclature. It brought uniformity to naming across the scientific world and is still followed today, governed by codes such as the ICBN (for plants) and ICZN (for animals).

›Reveal solutionSolution
Onion's binomial name is Allium cepa, following the two-word (genus + species) naming system of binomial nomenclature.
Binomial nomenclature, given by Carl Linnaeus, assigns every organism a two-part scientific name: the first word is the genus (always capitalised) and the second is the specific epithet (written in lowercase), both usually italicised or underlined. Onion belongs to the genus Allium and its specific epithet is cepa, giving Allium cepa.
