In the case of animals instead of division, Plasmodium is the genus name which has several species which exhibit unique morphological characteristics. It is considered much more accurate than the classes. With these vast numbers, it becomes necessary to classify them into groups lest the sheer number of different species becomes very hard to study. Each of the biologists who classified organisms, have done it by separating them into different groups according to various criteria. The presence of variety of plants in the form of different Taxas (specie, genera) is called diversity of plant. The purpose of this level is to find certain physical similarities amongst the various organisms within a kingdom. These categories are ranked on above the other, called hierarchy. ©2004-2020 Universal Taxonomic Services.

Each category is considered as the taxonomic unit and its represents a Taxon. For example, all of the animals in the Kingdom Animalia are split into multiple phyla (plural of phylum). Different plants have different morphology, physiology, cytology and anatomy. Considering the example of Plasmodium, it is a genus with multiple species that are similar to each other but differ from the species of another genus. Later age scientists began to work on classifying living organisms on the basis of their characteristics, which could be explained in many ways. Later, a Swedish botanist Carolus Linnaeus introduced Taxonomic Hierarchy Categories during the 18th Century, and this system of classification is followed globally till date. The organisms of a particular class are further separated into orders. Plant Taxonomy is a branch of science that continues to change as new species are being found almost every day. Taxonomy - Taxonomy - Ranks: The goal of classifying is to place an organism into an already existing group or to create a new group for it, based on its resemblances to and differences from known forms. The Genus or genera is even more specific when compared family and other tiers. The different kingdoms are Plantae, Fungi, Protista, Animalia, monera, and Archaebacteria. The system by which various taxonomic categories are arranged in a proper stepwise manner for the classification of plants and animals is called taxonomic or systematic hierarchy. The classification of living organisms based on similarities and dissimilarities is known as biological classification. 2012 [nom. taxa). It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). phylum is used. Homo is the genus name and sapiens is the species name. Taxonomic units at a given level are termed taxa (singular taxon). He classified animal on the basis of their habitat i.e., air, water, and land but that classification was not justified.

The different classes are class Reptilia, class Aves, class Mammalia, class Plants, and many others.
