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.
