Questions Related to nomenclature in classification

Linnaeus in his book "Species plantarum" (1753) proposed scientific names and Latin diagnosis of Mangifera indica, Saraca indica, Tamarindus indica, Rosa indica and Solanum nigrum. In the above case, how many species and genera respectively described by Linnaeus

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. (1) 7,5

  2. (2) 5,7

  3. (3) 5,5

  4. (4) 4,5

Show answer
Correct Option: C
Explanation:

Scientific description of an organism includes a two name or binomial system of Genus and species/specific epithet. The name of scientist who has described the genus and species is written in abbreviated form after the specific epithet. For example, Linnaeus is written as Linn, or L. All the Genera and species in the question have been described by Linneaus 

So, the correct answer is ' 5,5'

Polynomial classification has recently begun to replace the binomial system

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. True

  2. False

Show answer
Correct Option: B

Polynomial System of nomenclature was the older form of naming organisms before the advent of binomial system. In polynomial system, a generic name and specific name which consisted of many words were used. It was eventually found to be incompatible and hence was replaced by binomial system.
So, the correct answer is, 'False'.

  3. Letter 'L' signifies the taxonomist, Linnaeus.

  4. Letter 'L' is superfluous.

Show answer
Correct Option: C
Explanation:

Carl Linnaeus was a Swedish botanist, physician and zoologist, who laid the foundations for the mordern biological naming scheme of biological nomenclature. He is known as the father of taxonomy and is also considered one of the fathers of modern ecology. In botany, the author abbreviation used to indicate Linnaeus as the authority for species name. In older publications, sometimes the abbreviation "Linn" is found.

  4. Latin

Show answer
Correct Option: D
Explanation:

Scientific names are used as means of classifying or identifying scientific plants.

Linnaeus continued this practice. 

How many of the given features are associated with binomial nomenclature?

Plant nomenclature means

  1. To give names to plants without any rules.

  2. Nomenclature of plants under the international rules.

  3. Nomenclature of plants in local language.

  4. Nomenclature of plants in English language.

Show answer
Correct Option: B
Explanation:

Nomenclature is application of correct name to plants and taxonomic rank under the rule as drawn by ICBN (International Code for Botanical Nomenclature); option A is incorrect and B is correct. Scientific names formulated in Latin language are preferred over those in vernacular languages due to restricted use and application of these names in one or two languages and non-availability of vernacular names for all known plant species; this makes option C incorrect. Scientific names are not formulated in English but in Latin because latter one is a dead language and the meanings of words are not prone to changes as is the case with English; this makes option D incorrect. Thus, the correct answer is option B.
