Taxonomy is a science that deals with naming, describing and classification of all living organisms including plants. Classification is based on behavioral, genetic and biochemical variations. Characterization, identification, and classification are the processes of taxonomy.Organisms are classified into similar categories namely kingdom, phylum, class, order, family, genus and species.
Carolus Linnaeus is considered as the Father of Taxonomy. He is the one who developed a procedure to name and organize species. Even today this procedure is being followed. His contributions to taxonomy were
- Hierarchical classification system
- Binomial nomenclature system
Group of organisms with similar characteristics are categorized into species. Species are distinguished based on the morphological characters. For example, different types of mangoes belong to one species.There are millions of species in nature and hence it is difficult to identify and classify those species without having a proper procedure. Linnaeus classification system with some changes is used all over the world to classify things.
Linnaeus classification system
Linnaeus classified universe into three broad kingdoms namely animals, plants, and minerals. He classified nature into a hierarchy. He divided kingdoms into classes. Classes were divided into orders and orders were further divided into genus and genus finally divided into species. All organisms are identified and categorized into any of the above groups respectively and named accordingly. In this way, Linnaeus classification system works.
Alpha Taxonomy & Beta Taxonomy
Alpha taxonomy refers to the system of finding, identifying, characterizing and naming the Taxons. A taxon is a group of organisms which can be clubbed to form a single unit.
The term Alpha taxonomy is introduced by William Bertram in series of papers published in 1935 and 1937.
Beta taxonomy refers to the delimitation of species using sophisticated, investigative and laboratory techniques.
Plant taxonomy is one of the major branches of taxonomy. It is a science that deals with identification, classification and naming of plants.
As discussed earlier whole nature is classified into three kingdoms. One among them is the plant kingdom which is divided into two main categories i.e, plants which can produce seed and plants which cannot produce seeds. Plants which can produce seeds are basically flowering plants, conifers, ginkgos, and cycads. These are reproduced through pollination etc. Seedless plants include horsetails, ferns, and mosses etc. These are reproduced through spores.
Animal taxonomy is a science that deals with identifying, classifying and naming of plants. Animals are classified based on Linnaeus classification system. Taxonomists place them in the hierarchical order starting with kingdom and proceeds through phyla, classes, orders, family, genera, and species.
Taxonomists divided the animal kingdom into two main categories which include vertebrates and invertebrates. Invertebrates phylum includes arthropods, mollusks, and annelids. Vertebrates include mammals, birds, reptiles, fish, and amphibians.
