Binomial Nomenclature & Scientific Naming — NEET Biology
✅ Asked in NEET 2026We should remember here that as we explore new areas, and even old ones, new organisms are continuously being identified. As stated earlier, there are millions of plants and animals in the world; we know the plants and animals in our own area by their local names. These local names would vary from place to place, even within a country. Probably you would recognise the confusion that would be created if we did not find ways and means to talk to each other, to refer to organisms we are talking about. Hence, there is a need to standardise the naming of living organisms such that a particular organism is known by the same name all over the world. This process is called nomenclature. Obviously, nomenclature or naming is only possible when the organism is described correctly and we know to what organism the name is attached to. This is identification. In order to facilitate the study, number of scientists have established procedures to assign a scientific name to each known organism. This is acceptable to biologists all over the world. For plants, scientific names are based on agreed principles and criteria, which are provided in International Code for Botanical Nomenclature (ICBN). You may ask, how are animals named? Animal taxonomists have evolved International Code of Zoological Nomenclature (ICZN). The scientific names ensure that each organism has only one name. Description of any organism should enable the people (in any part of the world) to arrive at the same name. They also ensure that such a name has not been used for any other known organism. Biologists follow universally accepted principles to provide scientific names to known organisms. Each name has two components – the Generic name and the specific epithet. This system of providing a name with two components is called Binomial nomenclature. This naming system given by Carolus Linnaeus is being practised by biologists all over the world. This naming system using a two word format was found convenient. Let us take the example of mango to understand the way of providing scientific names better. The scientific name of mango is written as Mangifera indica. Let us see how it is a binomial name. In this name Mangifera represents the genus while indica, is a particular species, or a specific epithet. Other universal rules of nomenclature are as follows:
NTA tests your understanding of binomial nomenclature—the two-part scientific naming system (Genus + specific epithet) established by Linnaeus. Students often confuse the order or forget which part is capitalized (Genus is always capitalized, specific epithet is lowercase, e.g., Mangifera indica). They also mix up nomenclature (naming) with identification (describing organisms correctly). The key trap: NEET asks why we need standardized naming—remember it's to avoid confusion from local names varying by region. To get it right: Binomial names are universally accepted, ensure each organism has only one name worldwide, and follow ICBN (plants) or ICZN (animals) codes. This fundamental concept ensures consistent communication in biology globally.
Which one of the following statements is not true about the universal rules of binomial nomenclature?
