Questions Related to hierarchy of classification

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).

The botanical name of Berseem (Egyptian clover) is

  1. Lens esculenta

  2. Crotolaria juncea

  3. Cyamopsis tetragonoloba

  4. Trifolium alexandrinum


Correct Option: D
Explanation:
Trifolium alexandrinum is the scientific name of Egyptian clover, also called as  berseem clover. It is an annual clover cultivated mostly in irrigated sub-tropical regions, and used as fodder, mainly for cattle and milk buffalo. It was an important winter crop in ancient Egypt and was introduced into northern India in the early nineteenth century.

The botanical name of 'Sanjeevani' is

  1. Selaginella utricularia

  2. Selaginella bryopteris

  3. Selaginella crotalaria

  4. None of the above


Correct Option: B
Explanation:

Selaginella bryopteris is commonly known as sanjeevini or sanjivini booti. It is a lithophytic plant. It is used medicinally in India. The popular name sanjeevani, which translates as "one that infuses life" derives from the medicinal properties. 

Sanjeevani grows on the hills of tropical areas, particularly the Arawali Mountain terrains from east to west in India. The dry plants have traditionally been used as a remedy for several human health complications for centuries in India, particularly by tribal peoples. Traditional uses include relief from heat stroke, dysuria, irregular menstruation and jaundice.
