  1. Binomial nomenclature

  2. Vernacular names

  3. Synonyms

  4. Trinomial nomenclature

Show answer
Correct Option: A
Explanation:
Binomial Nomenclature system consists of a Generic name and a Specific name. Generic name is a noun which is unique to one kingdom but can be repeated across kingdoms. Specific name is usually an adjective and is unique to an organism. Therefore, Binomial system of nomenclature gives us vital information about the organisms.
So, the correct answer is, 'Binomial Nomenclature'.

Correct Option: C
Explanation:

The binomial nomenclature of the Touch-me-not plant is Mimosa pudica. This plant is known as touch me not plant because the plant shows a type of nastic movement. Whenever the plant is touched, the leaflets get folded. The stimulus is passed from one branch to the entire branch of the plants. The leaves of the complete plant get folded in response to the touch.

Thus, the correct answer is 'Mimosa pudica'.

  1. Not applicable to cyanbacteria.

  2. Not accepted by a number of countries.

  3. Universal with one specific name to each organism.

  4. Universal with two specific names to each organism.

Show answer
Correct Option: C
Explanation:

  • Binomial nomenclature system was proposed by Carl Linnaeus for the scientific naming of all the plants and animals. Linnaeus proposed the scientific name of plants in his book 'Species Plantarum'.
  • In binomial nomenclature, each scientific name has two components-generic names (genus) and specific name (species) E.g., Mangifera indica Linn. Mangifera is the genus name and indica is the species name.
So, the correct answer 'Universal with one specific name to each organism'

  1. 1930

  2. 1975

  3. 1978

  4. 1982

Show answer
Correct Option: C
Explanation:

The current system of International code of botanical nomenclature (ICBN) was adapted to assign the scientific name to plants. It was adapted in 1978 after the twelfth International Botanical Congress held in 1975 to follow the rules for naming the plants. The fifth International Botanical Congress was also held in 1930, at Cambridge (England). So, the correct option is C.

Select the incorrect statements:

  1. Viruses

  2. Plants

  3. Animals

  4. Both B and C

Show answer
Correct Option: D
Explanation:
  • The International Code of Biological Nomenclature is the set of rules and recommendations dealing with the formal scientific names that are given to plants and animals. 
  • Its intent is that each taxonomic group has only one correct name that is accepted worldwide. The value of a scientific name is that it is an identifier; it is not necessarily of descriptive value, or even accurate.
  • International code of Viral Nomenclature (ICVN) is applicable for viruses.
So, the correct option is 'Both B and C'.

Botanical names of plants are treated in Latin because

zoology why classification? nomenclature in classification introduction to plant kingdom history of classification nomenclature of animals

  1. Rules of nomenclature were framed by Italian botanists they were speaking Latin.

  2. It is very difficult to pronounce Latin names and they convey multiple meanings.

  3. Latin was the natural language of many European countries.

  4. Latin was a dead language, its word would convey precise meaning. It was the mother of all European languages and all the early botanical literature was in Latin.

Show answer
Correct Option: D
Explanation:

Linnaeus started nomenclature of plants in Latin. At the time of Linnaeus’ work, Latin, the language of science, was taught everywhere and was uniquely suitable for this system of naming plants and animals. European scholars throughout the continent spoke Latin as a common language between various European nations. It is also the mother of all European languages.

So, the correct option is 'Latin was a dead language, its word would convey precise meaning, it was the mother of all European languages and all the early botanical literature was in Latin'.

Which is correct depiction of ICZN?

  1. Homo Sapiens

  2. Homo sapiens

  3. homo sapiens

  4. homo Sapiens

  • Rules for nomenclature according to ICZN are 1)It consists of two parts one is the genus epithet and the other is species epithet 2)The genus name is always written first 3)The genus name must be capitalized 4)The species epithet is never capitalized 5)The entire two-part name must be written in italics
  • Hence Homo sapiens is the correct depiction of ICZN because according to ICZN rules it has two parts one is genus epithet(Homo) and species epithet(sapiens), Both the parts are in italics, Genus name starts with a capital letter and species name starts with small later.
  • So, the correct answer is 'Homo sapiens'
