Questions Related to introduction to plant kingdom

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.
So, the correct option is 'b and c'.

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'.

Which is correct depiction of ICZN?

  1. Homo Sapiens

  2. Homo sapiens

  3. homo sapiens

  4. homo Sapiens


Correct Option: B
Explanation:
  • The International Code of Zoological Nomenclature(ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of animals.
  • 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'

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.


Correct Option: B
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'.

A binomial nomenclature has  how many words/parts?

  1. Five

  2. Three

  3. Two

  4. One


Correct Option: C
Explanation:

  • Carolus Linnaeus gave a scientific naming system in which an organism is given a universally accepted name consisting of 2 parts/words.
  • The first part is the generic name and the second part is the (specific) species name.
So, the correct option is 'Two'.

Binomial system of nomenclature for plants is effective from

  1. 5.8.1771

  2. 1.5.1753

  3. 1.8.1758

  4. 6.7.1736


Correct Option: D
Explanation:

  • Binomial system of nomenclature for plants is effective from 6. 7. 1736.
  • Each name consists of 2 parts, genus and specific epithet.
  • The book Systema Naturae introduced the system of binomial nomenclature.
So, the correct option is '6.7.1736'.

Which of the following is a correct nomenclature?

  1. Felis domesticus

  2. Felis domestica

  3. Magnifera indicus

  4. Tamarindus indica


Correct Option: A,D
Explanation:

According to the conventions, suffix '-us' is used at the end of the binomial name at the end of specific epithet while writing the name of animals but is avoided while naming the plants.

So, the correct option is 'Felis domesticus' for Housefly while 'Tamarindus indica' is used for Tamarind taking above convention in consideration.

Binomial nomenclature consists of two words 

  1. Genus and species

  2. Order and family

  3. Family and genus

  4. Species and variety


Correct Option: A
Explanation:
  • Binomial Nomenclature proposed by Carl Linnaeus 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. 
So, the correct option is 'Genus and species'.

Linnaeus is credited with 

  1. Binomial nomenclature

  2. Theory of biogenesis

  3. Discovery of microscope

  4. Discovery of blood circulation


Correct Option: A
Explanation:
  1. Carl Linnaeus, a Swedish botanist, physician, and zoologist, laid the foundations for the modern biological naming scheme of binomial nomenclature. He is known as the father of modern taxonomy and is also considered one of the fathers of modern ecology.
    2. The theory of biogenesis was proposed by Louis Pasteur. He proposed that all life originated from pre-existing life. i.e., fishes laid eggs giving rise to more fishes.
    3. The first optical microscope was invented by Zacharias Janssen.
    4. William Harvey is associated with the discovery of blood circulation.
    So, the correct option is 'Binomial nomenclature'.
