Question

The Science of naming, grouping and classification plants and animals is known as
A. Cytology
B. Taxonomy
C. Exobiology
D. Virology

Answer 1

Taxonomy is the branch of science that deals with the principles, procedures of naming animals or organisms in different categories. We can also call it classification. Nomenclature is considered as a part of taxonomy but there is a difference as it is a sub-category of taxonomy. It defines the scientific names of organisms and naming of organisms according to their species and genus name. diversification, evolution and somewhat related to taxonomy but are completely different.

Complete answer:
Option A Cytology: according to scientists, cytology is nothing but cell biology in common. It is the study of structural and chemical and behavioral components of living components. Mostly cell study. It deals with the cell life cycle part of biology.
Option A is not correct.
Option B Taxonomy: identification of organisms comes under classification according to their species, genus name. classification is a part of a taxonomic group, as taxonomic groups define a variety of categories to deal with animals based on their characters and size, basically morphology.
Option B is correct.
Option C Exobiology: exobiology commonly known as evolution. To understand evolution, animals are not present on earth; they have been evolved from cosmic particles. The history of life forms and their growth is studied under the term called evolution. Evolution is a concept where all life forms are categorized according to their days on earth, determining how old they are. Different animals have different ages.
Option C is not correct.
Option D Virology: Virology is the study of virus and its related categories such as- viroid and virions etc.
Option D is not correct.

Hence, Option B is the correct answer.

Note:
As we discussed the evolution and evolutionary concepts, each animal holds a specific age or period from which they have been born or came into life. Different types of taxonomic categories are- class, order, family, genus and species. Different kinds of organisms and their diversities are called systematics.
