Question

Five kingdom classification is given by
(a)Morgan
(b)Whittaker
(c)Linnaeus
(d)Haeckel

Answer 1

The five-kingdom classification proposed by an American plant ecologist. He was the first to propose the five-kingdom taxonomic classification. He recognized an additional kingdom for the Fungi. This resulted in the five-kingdom system of classification.

Complete step by step answer:
R. H. Whittaker proposed the five-kingdom classification. In this classification living organisms are divided into five different kingdoms; Monera, Protista, Fungi, Plantae, and Animalia. The main criteria of the five-kingdom classification were cell structure, body organization, mode of nutrition and reproduction, and phylogenetic relationships. The kingdom is the second highest taxonomic rank, below domain. Kingdoms are divided into smaller groups called phyla. A species is a group of genetically similar and potentially inbreeding individuals, which share a common ancestry. Several similar species form a large category, called a genus, several similar genera form a still larger group called family, several families form order, and so on.

So, the correct answer is ‘Whittakker’.

Additional information: -Linnaeus classified all living organisms into two kingdoms; Plantae and Animalia. This is referred to as the two kingdom classification. Two kingdom system does not differentiate between unicellular & multicellular organisms.
-Haeckel's three kingdoms were Animalia, Plantae, and Protista. He proposed protista as a new kingdom to accommodate organisms exhibiting characters either common to both plants and animals or unique to them.
-The six kingdom classification were Plants, Animals, Protists, Fungi, Archaebacteria, Eubacteria. Carl Woese and colleagues proposed six kingdom classification. Here kingdom monera is replaced by kingdoms bacteria and archaea.

Note:
-Herbert F. Copeland proposed a four-kingdom classification. He created the novel Kingdom Monera of prokaryotic organisms.
-Thomas Cavalier-Smith proposed the eight kingdom classification. The eight kingdoms are; Eubacteria, Archaebacteria, Protozoa, Chromista, Fungi, Plantae, and Animalia.
-Biological classification is the ordering of organisms into definite groups or sets based on their similarities, interrelationships, etc.
