Question

state the demerits of whittaker's classification

Answer 1

Demerits:
- The classification of kingdoms Monera and Protista are problematic. For one both the kingdoms include organisms with and without cell wall and ones that are autotrophic and heterotrophic.
- Viruses do not get a proper classification.
- Slime moulds, in spite of being considerably different from the rest of its counterparts in the kingdom, have been classified under Protista.
-  Certain organisms under Protista are not eukaryotic, rather mesokaryotic.

Answer 2

HEY MATE....

Demerits of R. H. Whittaker 5 Kingdom Classification

·          The five-kingdom classification has certain drawbacks also, particularly with reference to the lower forms of life.

·          The kingdoms Monera and Protista include diverse, heterogeneous forms of life. In both the kingdoms there are photosynthetic (autotrophic) as well as non-photosynthetic (heterotrophic) organisms. Both the kingdoms include organisms which have cells with cell wall as well as without cell wall.

·          None of the three higher kingdoms include a single ancestor of all its forms.

·          Multicellular lines have originated from protistans several times.

·          Unicellular green algae like Volvox and Chlamydomonas have not been included under Protista because of their resemblance to other green algae.

·          Slime moulds differ totally from other members of Protista in their general organization.

·          Viruses have not been given proper place in this system of classification.
