  2. Species Plantarum

  3. Genera Plantarum

  4. Philosophia Botanica


Correct Option: D

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


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'.

The binomial nomenclature of the Touch - me - not plant is

  1. Solanum nigrum

  2. Aegle marmelos

  3. Mimosa pudica

  4. Acalypha india


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'.

Binomial of vilvam is 

  1. Acalypha indica

  2. Aegle marmelos

  3. Cissus quadrangularis

  4. Mimosa pudica


Correct Option: B
Explanation:
The binomial nomenclature is the system which names the organisms with the help of two words which includes the genus and the species. The binomial name of Vilvam is Aegle marmelos. This is commonly known as the golden apple or stone apple. This fruit is known to have medicinal properties. 
Thus, the correct answer is option B. 

Binomial nomenclature is 

  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.


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'

The current system of International Code of Botanical Nomenclature was adapted

  1. 1930

  2. 1975

  3. 1978

  4. 1982


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:
(a) Lower the taxon, more are the characteristics shared by members.
(b) Order is an assemblage of genera which have a few similar characters.
(c) Cat and dog belong to same family of felidae.
(d) Binomial nomenclature was introduced by Carolus Linnaeus.

  1. b and c

  2. c and d

  3. a and d

  4. b, c and d


Correct Option: A
Explanation:

An order is the assemblage of families.

The cat belongs to the family Felidae and dog belongs to the family Canidae. Both dog and cat belong to the same order Carnivora.

International code of 'Biological Nomenclature' is applicable to

  1. Viruses

  2. Plants

  3. Animals

  4. Both B and C


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

  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.


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'.
