Classification Quiz

Classical systematics is a type of classification that only takes into account morphological characters, and considers species to be a static and immutable entity. New systematics, on the other hand, takes into consideration all types of characteristics like morphological, cytological, physiological ecological, biochemical and genetical. It is also called integrated taxonomy.

Binomial nomenclature is a system of naming species using two Latin words, the genus name and the species name. It was developed by Carolus Linnaeus in his book Systema Naturae, first published in 1758.

Chemotaxonomy is the use of chemical analysis or tests of plant parts and products in the study of taxonomy. It is used to determine the relationships between organisms based on their biochemical characteristics.

Classification is the grouping or categorizing of organisms based on their similarities and dissimilarities for the convenience of study. It is important in the study of organisms due to the high number of species (1.7 million) and it helps to organize and understand the relationships between different organisms.

Taxonomy is the study of identification, nomenclature, and classification of organisms. It is related to systematics because systematics includes taxonomy as well as the study of evolutionary relationships among organisms.

Systematic botany is the systematics of plants, which is the study of diversity of organisms and their evolutionary relationships. It relates to the study of plants because it helps to classify and understand the relationships between different plant species.

The five codes of nomenclature are International Code of Botanical Nomenclature (ICBN), International Code of Zoological Nomenclature (ICZN), International Code for Nomenclature of Bacteria (ICNB), International Code of Viral Nomenclature (ICVN), and International code of Nomenclature for Cultivated Plants (ICNCP). They cover the naming of botanical, zoological, bacterial, viral, and cultivated plant organisms, respectively.

A scientific name consists of two words, first genus and second species. They should not have less than three letters and more than twelve letters. The generic name is always written first, which is like a noun having its first letter in capital form. The generic name is always unique for a living organism. The specific name is written after the generic name, which is like an adjective having its first letter in small form. It can be single or compound (e.g., Hibiscus rosa sinensis). The gender of the specific name follows the gender of the generic name, e.g., Mangifera indica, Tamarindus indica. The biological or scientific name is always printed in italics whereas it is underlined while handwritten. The two-word scientific names are generally followed by the name of the discoverer or author. The author’s name can be full or abbreviated (i.e., Mangifera indica L., Homo sapiens Linn., Cycas circinalis Linnaeus). Author’s name is not italicised.

Trinomial nomenclature is the naming of organisms using three words, which include generic, specific, and sub-species part. It is especially used for naming animals, and examples include Homo sapiens sapiens and Puccinia graminis tritici.

Classical systematics considers species to be fixed and only uses morphological characters, while new systematics takes into account various characteristics like morphological, cytological, physiological ecological, biochemical and genetical.
