Question

Principles and rules of classification are studied under
(A) Systematics
(B) Natural classification
(C) Nomenclature
(D) Taxonomy

Answer 1

Hint: The plant or the animal organisms that are newly discovered are first identified and named. The naming of the organism is based on the nomenclature and these are classified depending upon their characteristics and nature. This process is done by the rules followed in the taxonomy.

Complete Answer:
(A) Systematics: It is also the branch of biology which deals with the study of the diversification of the living organism over time.

(B) Natural classification: It is the process in which the organisms are classified based upon their similarities in the behavior, structure etc. It is obtained through the taxonomy.

(C) Nomenclature: It is the process of naming the organisms that are discovered. This name is the combination of two names as the species and the genus name. The genus names start with the capital letter and the species name is not capitalized.

(D) Taxonomy: It is the branch in biology which deals with the study of the principles and procedure for the classification of all the organisms known into the groups based on the similarities of the origin, behavior and the structure etc. The objective of the taxonomy includes identification, nomenclature, and classification.
From the above explanation it is clear that the principles and the rules are studied under taxonomy.

Thus, the option (D) is correct.

Note: For example, the scientific name of mango is Mangifera indica. In which the Mangifera is the name of the genus it belonged to and the indica is the name of the species. This system of binomial naming was proposed by Carl Linnaeus.
