Question

Which of the following is not one of the five kingdoms of R. H. Whittaker's classification system?
A. Animalia
B. Monera
C. Protista
D. Chordate

Answer 1

Hint: The primitive unicellular species were the prokaryotic group, while the advanced organisms were the eukaryote group. The main parameters of the Whittaker system were: - cell type, organization thallus, diet, reproduction & the phylogenetic connection. Robert. H. Whittaker suggested in 1969 five-kingdom systems of organism classifications.

Complete answer:
Classification of the five Kingdoms of R. H. Whittaker is made up of five kingdoms: Monera, Protista, Fungi, Flora, and Fauna. With the exception of Monera, all four kingdoms are eukaryotes. Therefore, there are four kingdoms of eukaryotes. The 5 kingdoms have been categorized by form and function. Monera is exposed to prokaryotic tissue because they lack a genuine nucleus and membrane organelles.
Previously, fungi were divided into plants, but they were found to differ totally from plants after the analysis, which was grouped into fungi. Bacteria are primarily and often prokaryotes. Eukaryotes are organisms that, together with a true nucleus bounded by a nuclear membrane, have membrane-bound cell organelles. The cell organelles are special and multicellular to the eukaryotes. The most common type of eukaryotes is mammal, plant, and fungi, while protists are other eukaryotes. They can reproduce by sexual and asexual methods (meiosis and gamete).
Hence, option D-Chordates is the correct answer.

Note: Carolus Linnaeus first proposed a classification of species based on the kingdoms in his classification of the two kingdoms. In the Linnaean classification system, all modern classification systems have their origins. In apparent physical characteristics, the Linnaean system was found to be based on similarities. It is composed of a taxonomic hierarchy, from the kingdom to the organisms. A specific two-word Latin name is given to each species.
