Question

What is taxonomy?

Answer 1

Hint: Taxonomy is a stream of biological sciences. It refers to the way various organisms can be classified into certain categories.

Complete answer:

Taxonomy is a branch of biological sciences. It is the way species are categorised on the basis of similarity and dissimilarity, and species are named.</b> It is divided into taxa by the organism. In taxonomy, the principal ranks are domain, kingdom, phylum, class, order, family, genus and species.

The subject basically deals with concepts, rules and procedures for classifying organisms. For classification, we have to identify and name an organism. Hence, the first step in taxonomy becomes identification, and then comes nomenclature and finally classification.

A hierarchy of graded taxonomic ranks, called taxa, consists of the Linnaean classification system. Several lower taxa may come under each taxon; these are normally distinguishable on the basis of some common features.

Additional information
Cytotaxonomy is based on cytological information as chromosome number, structure and behaviour. Chemotaxonomy uses the chemical constituent of the plant to resolve the confusion.

Note:
Classification is a mechanism in which species that are similarly related are grouped in a group. The classes that have links are put into larger groups. Taxonomic groups are known as the different grouping levels or grades of classification. Nomenclature refers to the assigning a universal scientific name.
