Questions Related to different types of classifications

Organic compound first evolved on earth and required for origin of life were :

  1. Urea and amino acids

  2. Proteins and nucleic acids

  3. Proteins and amino acids

  4. Urea and nucleic acid


Correct Option: B
Explanation:
  • Proteins and nucleic acids are the two most basic compounds for the sustenance of life. 
  • Proteins provided a limiting membrane and boundary to primitive entities and nucleic acids were important information molecules, which were required to build self-replicating entities. Option B is correct

State whether the following statements are true or false.
Classification allows subsequent identification of a species

  1. True

  2. False


Correct Option: A
Explanation:

Classification helps orderly and hierarchical grouping of organisms into different taxa based on their similarities and differences and therefore helps in identification of species 

So, the correct answer is 'True'

Choose the correct answers from the alternatives given.
All of the following are true regarding systematics except that:

  1. it is the study of the diversity of organisms at all levels of organisation

  2. it is the specific study of identification, naming, and classification of organisms

  3. it relies on data from the fossil record, homology, and molecular data

  4. it utilises protein, DNA and RNA comparisons to determine relatedness of individuals


Correct Option: B

Which of the following is a drawback of four-kingdom classification given by Copeland?

  1. There was no separate kingdom for prokaryotes

  2. Fungi was included in plantae

  3. Fungi was included in animalia

  4. None of the above


Correct Option: B
Explanation:
Copeland proposed the four kingdom classification. He grouped all living organisms into four kingdoms, namely Kingdom Monera, Kingdom protista, Kingdom Metaphyta(Plantae) and Kingdom Metazoa(animalia).
He  included fungi in plantae despite being heterotrophic and having chitinous cell wall.
So, the correct option is 'Fungi was included in plantae'.

Initially, classification of living things was done as

  1. Plants

  2. Animals

  3. Monera

  4. Both A and B


Correct Option: D
Explanation:

The living organisms were classified into two kingdoms, plants and animals. The organisms which can perform photosynthesis and can prepare their own food were placed in kingdom Plantae. The organisms which are heterotrophic and can perform locomotion were placed in kingdom Animalia. 

Thus, the correct answer is option D. 

The two kingdom classification of Linnaeus is proved to be ineffective in the case of which of the following organism/s?

  1. Fungi

  2. Lichens

  3. Euglena

  4. All of the above


Correct Option: D
Explanation:

In the two-kingdom classification given by Linnaeus, all organisms were classified into plants and animals. This system, however, did not distinguish between eukaryotes and prokaryotes/unicellular and multicellular organisms/ photosynthetic and nonphotosynthetic organisms in which a large number of organisms did not fit. Lichens and fungi were classified under Plantae and euglena under Animalia.

So, the correct option is 'all of the above'.

Association in which both the organisms get benefited is __________________.

  1. Commensalism

  2. Mutualism

  3. Ammensalism

  4. Parasitism


Correct Option: B
Explanation:

Mutualism refers to ecological association between two organisms of different species which mutually get benefitted by their association. In commensalism, one organism gets benefitted and the other is neither benefitted nor harmed. In amensalism, one organism is destroyed and the other remains unaffected. In parasitism, one organism (parasite) lives inside other organism (host) and harms its host.

Correct answer is B.

The rose wood tree of India is

  1. Dalbergia sissoo

  2. Pinus roxburghii

  3. Tamarindus indica

  4. None of the above


Correct Option: A
Explanation:

Dalbergia sissoo or Rosewood tree is the native of the Indian subcontinent and southern Iran. It is an evergreen rosewood tree, also known as Sheesham, sisu, tahli, Tali. It is primarily found growing along river banks below 900 meters. The temperature in its native range averages 10–40 °C. It can withstand average annual rainfall up to 2,000 millimeters (79 in) and droughts of 3–4 months. Thus, the correct answer is option A.

Two kingdom classification was given by ________

  1. Linnaeus

  2. Mendel

  3. Whittaker

  4. None of these


Correct Option: A
Explanation:

According to the old classification which was given by linnaeus (1707 - 1778), The entire world of living organises nearly divided into two kingdoms. Kingdom plantae (including all plants) and kingdom animalia (including all animals).
