Questions Related to nomenclature in classification

The publication of Linnaeus "Species plantarum" is the starting point for nomenclature of

  1. Moss

  2. Spermatophyta

  3. All organisms

  4. Fungi


Correct Option: B
Explanation:

  • "Species Plantarum", a book written by Carolus Linnaeus (Swedish naturalist), contains nearly 5900 species of plants and it is the starting point for the nomenclature of flowering plants (spermatophytes) and ferns i.e, plants. 
  • Species Plantarum was the first botanical work to consistently apply the binomial nomenclature system for the large group of plants.
So the correct option is spermatophyta.

What does Paris code and Vienna code refer to?

  1. Nomenclature of plants

  2. Nomenclature of animals

  3. Both of the above

  4. Anticode


Correct Option: A
Explanation:

The binomial system of nomenclature has been an important factor in the development of taxonomy. Before the middle of 18th century the names of plants were polynomials consisting of several words. The confusion arising due to this emphasised the need of a code of nomenclature by which the naming of plants might be regulated. Many codes have been proposed, buy only two have received the support of international conferences, the Paris Code of 1867 and the Vienna Code of 1905. These two codes have been a great help in stabilising nomenclature.

ICBN was adopted in 

  1. 1951

  2. 1978

  3. 1971

  4. 1985


Correct Option: B
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.

Plants are given Latin names because it is a 

  1. Simple language

  2. Common language

  3. Dead language

  4. None of the above


Correct Option: C
Explanation:

In the mid eighteenth century, the Swedish botanist Carl Linnaeus devised a system in which every living species was given a two part Latin name. Latin, was chosen because it was a dead language, fixed and not changing over time. Thus, we can rely on a Latin name to mean exactly the same thing that it did 300 years ago. The first word in a scientific name, is that of the genus. The second word of a scientific name identifies an individual species.

In a scientific name, the name of the author is printed in

  1. Capital letters

  2. Bold(antics)

  3. Italics

  4. Roman


Correct Option: D
Explanation:

In the scientific name genus and species name written in italic and name of auther is printed in Roman.

Example, Mangifera indica linn. here Mangifera is genus, Indica is species and Linneous is auther name.

Naja naja is the scientific name of Indian Cobra in a:

  1. Tautonym.

  2. Autonym.

  3. Synonym.

  4. Both (B) and (C).


Correct Option: A

Which one of the following is wrong statement?

  1. Growth and reproduction are mutually exclusive in higher plants and animals.

  2. Metabolism and consciousness are defining characteristics of living organisms unlike growth and reproduction.

  3. The standard size of a herbarium sheet is $29 \, \times \, 41cm$.

  4. Binomial system of nomenclature for plant is effective from 1735.


Correct Option: D
Explanation:

Option $D$ is wrong statement.

Binomial system of  nomenclature for plant is effective from $1758$.
Binomial system of nomenclature is a universal name given to any organism. This consists of two Latin words which is written in italics or underlined to denote a species that is to be denoted. This system of naming was introduced by Carl Linnaeus.

Consider the following statements regarding scientific name: (i) The idea of binomial nomenclature was first introduced by Gaspard Bauhin. (ii) Scientific names are always in Greek. (iii) The first name in scientific name is generic name. (iv) Generic and specific name starts with small letters.
Segregate the above statements as true (T) or false (F) by selecting the correct option:

  1. FFTF.

  2. TTTT.

  3. FFFT.

  4. FTFT.


Correct Option: A

Binomial nomenclature is  _____________-

  1. Two words in name of species

  2. Two names local and specific

  3. Feeding over the same food

  4. Reproductively isolated


Correct Option: A
Explanation:

Binomial nomenclature is a two-term naming system that uses two different terms to name the species, plants, animals and living organisms. Binomial nomenclature is also known as Binary nomenclature. The two terms consists of a generic epithet which is genus (category) of that species, and specific epithet which indicates the species itself. This two-terms naming system can also use some other different languages to create such scientific names. These scientific names are unique and help in identifying organisms analyser in the world.
