Question

Which of the following gives vital information about the plant?
A. Binomial nomenclature
B. Vernacular names
C. Synonyms
D. Trinomial nomenclature

Answer 1

Hint:- Nomenclature can be defined as the process of giving scientific names to plants and animals. An organism must be known by the same scientific name throughout the world. The standardization of organisms and plant names is very essential for advancement of biological sciences.

Complete answer: Binomial nomenclature deals with correct naming of an organism. The method was so convenient to the biologist all over the world that it was universally accepted.
According to this system, every name comprises two words: a substantive ‘Genus’ and an adjective Species. Genus is common to all the species. The name of the species is based on some fixed and definite characters.
Most of the generic names are Latin and Greek words which usually indicate some property possessed by plants or animals. Sometimes generic names are also given on the names of distinguished Botanist and Zoologist. Specific names follow the genus and are written in small letters except when they are indicative of important personages. The name of the author is described after the name of the species, e.g. Solanum tuberosum Linn.
Vernacular names are the common names of the organisms that differ from region to region and language to language. These may be misleading sometimes.
In trinomial nomenclature three words are used for naming the organism. These include generic name, specific and subspecies part, for example Homo sapiens sapiens.
Synonyms are not used in botanical nomenclature.

So the correct answer is 1. Binomial nomenclature.

Note:- The present system of binomial nomenclature dates back from the time of Linnaeus who discussed it in 1753 in Species Plantarum. Candolle in his ‘Theorie elementaire de la botanique’ gave significant works on nomenclature after Linnaeus.
