Botany MCQs for NEET — Practice Questions with Answers

In biological classification, the category below the level of family is genus. The hierarchy of classification is kingdom, phylum, class, order, family, genus, and species.

Carl Linnaeus was the first botanist to give binomial nomenclature. Binomial nomenclature is a formal system of naming species of living things by giving each a name composed of two parts. Linnaeus's system of binomial nomenclature is still in use today, with modifications.

A taxon is a unit of classification in biological taxonomy. It represents a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Taxa (plural of taxon) are arranged in a hierarchy from kingdom down to subspecies, and they include categories such as family, genus, and species.

Species is the most specific level of classification in biological taxonomy. Members of the same species are the most closely related and can interbreed. Higher taxonomic levels like genus, family, and class contain increasingly diverse groups of organisms.

Phylum covers a greater number of organisms compared to order, family, and genus. The taxonomic hierarchy is arranged from broad to specific as follows: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Thus, phylum encompasses a larger group of organisms.

Inbreeding is possible between two members of the same species. Members of the same species have the ability to interbreed and produce fertile offspring. Higher taxonomic categories such as genus, family, or order include organisms that are too distantly related to interbreed.

The first step in taxonomy is identification. Identification involves determining the identity of an organism and placing it into a predefined category based on its characteristics. This step is crucial as it allows for the organism to be classified and named appropriately.

A taxon is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Therefore, 'taxon' can include all ranks of hierarchy such as species, genus, family, order, class, phylum, and kingdom.

The smallest unit of classification is the species. A species is defined as a group of individuals that actually or potentially interbreed in nature. It is the most specific level of organism classification and contains organisms that are very closely related.

The basic unit of classification in biological taxonomy is the 'species.' Species are groups of organisms that can interbreed and produce fertile offspring. This concept is fundamental in biology and helps in identifying and categorizing the vast diversity of life on Earth.
