Question

Assertion:
Systematic is the branch of biology that deals with the classification of living organisms.
Reason:
The aim of classification is to group the organisms in an orderly manner.
A. Both Assertion and Reason are correct and Reason is the right explanation for Assertion.
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
C. An assertion is correct but Reason is incorrect.
D. Both Assertion and Reason are incorrect.

Answer 1

Taxonomy and evolution are two aspects of systematic biology. Classification of organisms allows for establishing relations between past and present organisms. Nomenclature makes the recognition of different organisms easy. All these components come under the branch of systematic biology.

Complete answer:
The branch of systematics deals with the classification, nomenclature, and evolution of organisms. It not only considers the morphological and anatomical characters but also the molecular components and genetics. The behavioral and evolutionary aspects are also included in systematic biology.
Biological systematic studies the diverse forms of living organisms, both present and past. It also focuses on studying the relationships shared by organisms over time. These relationships can be visualized through evolutionary trees or phylogenetic trees. The systematic branch is also useful in understanding the evolutionary history of life on Earth.
In the classification branch of systematic, organisms are placed in an orderly or hierarchical manner to give them a certain identifiable position. This is specifically known as a taxonomic hierarchy. Also, systematic provides scientific names to the organism. It provides a description and ordering of the organisms based on certain characters. Systematic also helps in establishing conservation guidelines. Thus, it explains various preservation and protection measures for biodiversity.
Hence, we can conclude that both Assertion and Reason are correct and reason rightly explains the Assertion.

So, option A) is the right answer.

Note: There are several branches of systematic biology like numerical systematics which is based on the bio-statistical method of identification and classification. Biochemical systematic deals with biochemical analysis of organisms for their classification. Experimental systematic deals with evolutionary units of identification and mutations are considered the evolutionary units.
