  4. Out of seven taxomic category, two are used to denote scientific name generally

A Correct answer
Explanation

Scientific names must follow Latinized rules and are not written in 'any' language. The other statements are generally accepted rules of binomial nomenclature, making A the incorrect statement requested.

A scientific name contains information about its

  1. Family and species

  2. Genus and species

  3. Phylum and order

  4. Class and family
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A scientific name contains information about its genus and species.
The scientific name of an organism is used to identify it anywhere in the world. Under binomial system of nomenclature, each organism has scientific name consisting of two parts. First part is genus and second part is the species. For example- the scientific name of mango is Mangifera indica, scientific name of house fly is Musca domestica.

In binomial nomenclature, the first name refers to

  1. Order

  2. Class

  3. Genus

  4. Species
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In binomial nomenclature, the first name refers to the genus. The second part is a species name.

The first part of the binomial, the genus name, is always written with an initial capital letter. In current usage, the second part is never written with an initial capital.

A binomial scientific name contains 

  1. Names of genera and family

  2. Names of genera and species

  3. Names of species and class

  4. Names of class and kingdom
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Binomial nomenclature is the formal naming system for living things that all scientists use. It gives every species a two-part scientific name. For example, a ladybug found in the United States goes by the fancy name of Harmonia axyridis. The first part of a scientific name, like Harmonia, is called the genus. A genus is typically the name for a small group of closely related organisms. The second part of a scientific name, axyridis in this example, is the specific epithet. It is used to identify a particular species as separate from others belonging to the same genus. Together, the genus plus the specific epithet is the full scientific name for an organism. 

Therefore, the correct answer is option B.

Binomial nomenclature means indication of the name of an organism's 

  1. Order and family

  2. Family and genus

  3. Genus and species

  4. Species and variety
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Binomial Nomenclature is the system of providing organisms with appropriate and distinct names consisting of two words, first generic and second specific
  • The generic word is also called genus and acts like a noun and its first letter is written in the capital form
  • The specific epithet represents the species. It is like an adjective and its first letter is written in a small form
  • So the correct option is 'genus and species'.

According to binomial nomenclature system, scientific name includes two terms. They are

  1. Genus and species

  2. Class and order

  3. Genus and phylum

  4. Species and order

A Correct answer
Explanation

On the basis of hierarchy of characteristics, the last two units of classification are genus and species. The organism belonging to same genus and species are very much similar.

In which book 'binomial nomenclature' has been used for the first time?

  1. Histoire naturelle

  2. Systema naturae

  3. Historia naturalis

  4. Historia plantarum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The 10th edition of 'Systema Naturae' was a book written by Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced the binomial nomenclature for animals.
Thus, the answer is option (B) - 'Systema naturae'.

Linnaeus published his concept of binomial nomenclature first in 

  1. Systema Naturae

  3. Genera Plantarum

  4. Philosophia Botanica
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Philosophia Botanica was published by the Swedish naturalist Carl Linnaeus in 1751 who greatly influenced the development of botanical taxonomy and systematics. It is the first textbook of descriptive systematic botany and botanical Latin. It also contains Linnaeus's first published description of his binomial nomenclature.

So, the correct option is 'Philosophia Botanica'.

Which of the following gives vital information about the plants?

  1. Binomial nomenclature

  2. Vernacular names

  3. Synonyms

  4. Trinomial nomenclature
Reveal answer Fill a bubble to check yourself
A Correct answer
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'.

International code of 'Biological Nomenclature' is applicable to

  1. Viruses

  2. Plants

  3. Animals

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
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

  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.
Reveal answer Fill a bubble to check yourself
D Correct answer
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'.

Binomial nomenclature means 

  1. One name given by two scientists.

  2. One specific name consisting of a genus and specific epithet.

  3. Two names, one latinised, other of person.

  4. Two names, one scientific, other local.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Binomial Nomenclature is the method of naming a particular organism by a single standard name known all over the world. The first word represents the genus while the second component represents specific epithet. The first word of the generic name starts with a capital letter and specific epithet starts with a small letter.

So, the correct option 'One specific name consisting of a gene and specific epithet'.

  1. 5.8.1771

  2. 1.5.1753

  3. 1.8.1758

  4. 6.7.1736
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Binomial system of nomenclature for plants is effective from 6. 7. 1736.
