Number of series distinguished by Bentham and Hooker is subclass monochlamydeae is

  1. $3$

  2. $5$

  3. $7$

  4. $8$


Correct Option: D
Explanation:

The group monochlamydaea was one of three within the Dicotyledons, the others being Polypetalae and Gamopetalae. It included plants with flowers that had either a calyx or corolla, but not both. Though, it was later abandoned.

The number of series distinguished by Bentham and Hooker in subclass monochlamydeous were eight.
So, the correct option is '8'.

A taxonomic species distinguished on the basis of morphological characters is

  1. Morphospecies

  2. Biospecies

  3. Linneon

  4. Neontological species


Correct Option: C
Explanation:
  1. Morphospecies are groups of individuals that are morphologically similar and clearly distinguishable from individuals of other groups.
    2. A group of interbreeding individuals that are isolated reproductively from all other groups is called Biospecies.
    3. Linneon are the taxonomic species distinguished on the basis of morphological characters.
    4. Those species which are present in the living world are known as neontological species.
    So, the correct option is 'Linneon'.

Science dealing with study of external form, size, colour, structure and relative position of various parts of an organism is?

  1. Anatomy

  2. Morphology

  3. Entomology

  4. Histology


Correct Option: B
Explanation:

A. The branch of science concerned with the bodily structure of humans, animals, and other living organisms, especially as revealed by separation of parts is called Anatomy

B. Morphology is the branch of science dealing with the study of the form and structure of organisms and their specific structural features.
C. Entomology is the study of insects.
D. Histology is the study of cell structure and tissues of an organism.
So, the correct answer is 'Morphology'.

State whether the following statements are true or false.
Museums serve an important role as centers of documentation.

Correct Option: A

Match column I with column II and select the correct option from the given codes.

Column I Column II
A. John Ray (i) Gave the concept of new systematics
B. C. Linnaeus (ii) First described species as a unit of classification
C. Aristotle (iii) Father of Zoology
D. Julian Huxley (iv) Introduced binomial nomenclature
  1. A-(i), B-(ii), C-(iii), D-(iv)

  2. A-(iv), B-(ii), C-(iii), D-(i)

  3. A-(ii), B-(iii), C-(i), D-(iv)

  4. A-(ii), B-(iv), C-(iii), D-(i)


Correct Option: D
Explanation:

First described species as a unit of classification - John Ray

binomial nomenclature i- name Carl Linnaeus 
Father of Zoology - Aristotle
Gave the concept of new systematics - Julian Huxley
So, the correct option is 'A-(iv), B-(ii), C-(iii), D-(i)'.

  1. Population of individuals having same genotypes and

    phenotypes

  2. A group of individuals inhabiting a geographical area

  3. A group of interbreeding populations

  4. Population of one type


Correct Option: C
Explanation:

Species are the groups of individuals that sexually interbreed or are potentially interbreeding form.

So, the correct answer is option D.

Which of the following scientist has made a significant contribution in the field of classification?

  1. Pasteur

  2. Oparin

  3. Darwin

  4. Linnaeus


Correct Option: D
Explanation:

Pasteur, Oparin and Darwin are the scientists who are known for their contributions in the field of microbiology, biochemistry (theory for the origin of life) and evolution (origin of species) respectively. Carl Linnaeus gave the Linnaean taxonomy and binomial nomenclature. The classification and the nomenclature were published in the book Systema Naturae which was written by Carl Linnaeus. The binomial nomenclature for the classification of the organisms is considered as an important contribution. 

Thus, the correct answer is option D. 

Aristotle belonged to

  1. England

  2. France

  3. Greece

  4. Belgium


Correct Option: C

    2. The original classification of living organisms was developed by Aristotle.
    3. He made contributions to logic, metaphysics, mathematics, physics, biology, botany, ethics, politics, agriculture, medicine, dance, and theatre.
    So, the correct option is 'Greece'.
