There are different types of animal and plant species around us. They are classified on the basis of their similarities and dissimilarities scientifically. Taxonomy is a branch of science that deals with naming, describing, and classifying organisms and includes all plants, animals, and microorganisms of the world. The current taxonomic system has eight levels of hierarchy, the arrangement of them from lowest to highest are: species genus family order class phylum kingdom domain

Identification helps to distinguish the organisms from another organism. Classification can be best defined as a process that helps to group anything into distinct categories based on its characteristics. Systematics can be best defined as a study of different kinds of organisms and their derivatives. It also depicts the relationship among them. This word is derived from the latin word ‘systema’. Systematics also exhibits the evolutionary relationships between organisms.

Biologists follow universally accepted principles to provide scientific names to known organisms. The system of providing a name with two components is called binomial nomenclature. It has generic name and specific epithet. This process of naming was first given by Carolus Linnaeus. For example, the scientific name of mango tree is Mangifera indica .
