Question

a. State the merits of Whittaker’s method of classification.

Answer 1

Merits of R. H. Whittaker 5 Kingdom Classification

------------------------------------------------------------------------------------------------

The grouping of all the unicellular eukaryotes under a special category Protista helped in solving various problems.

------------------------------------------------------------------------------------------------

The separation of prokaryotes into a special kingdom helped in the differentiation of organisms

------------------------------------------------------------------------------------------------

The cellular organization is clearly mentioned which will be helpful for the studies in microbiology. 

Answer 2

Merits of R. H. Whittaker 5 Kingdom Classification·          This system of classification looks more scientific and natural because of the following considerations: ·          It is largely the most accepted system of modern classification mainly because of the phylogenetic placing of different groups of living organisms ·          Separation of prokaryotes into an independent kingdom is justifiable because they differ from all other organisms in their general organization. ·          Grouping of all unicellular eukaryotes under the kingdom Protista has solved many problems, particularly related to the position of organisms like Euglena. ·          Elevation of the group fungi to the status of a kingdom is justifiable since fungi totally differ from other primitive eukaryotes like algae and protozoans. ·          The kingdoms plantae and animalia are now more homogeneous groups than they were in the two kingdom classification as it shows the phylogeny of different life styles. ·          The five-kingdom classification gives a clear indication of cellular organization and modes of nutrition, the characters which appeared very early in the evolution of life.
