Consider the following statements I. Biological classification is the scientific ordering of organisms in a hierarchial series of groups on the basis of their relationships, $i.e$., morphological, evolutionary and others II. Whittaker classified organisms on the basis of autotrophic and heterotrophic mode of nutrition III. In five kingdom system of classification, living organisms can be divided into prokaryotic and eukaryotic cells on the basis of cell structure Which of the statements given above are correct?

Question

Dr. Abubacker · Accepted Answer

Biological classification is the scientific procedure of arranging organisms, into groups and sub-groups on the basis of their similarities and dissimilarities and placing the groups in a hierarchy of categories Whittaker has used five criteria for delimiting the different kingdoms (i) Complexity of cell structure, i.e., prokaryotic and eukaryotic (ii) Complexity of body structure or structural organisation of unicellular and multicellular (iii) Mode of nutrition, which is divergent in multicellular kingdoms, photoautotrophy in Plantae, absorptive heterotrophy in Fungi and ingestive heterotrophy in Animalia (iv) Ecological life style like producers (Plantae) decomposers (Fungi) and consumer (Animalia) (v) Phylogenetic relationships
