Question

A drawback of the 'five kingdom classification' is

• A. Inclusion of unicellular eukaryotes in the kingdom of Protista.
• B. Inclusion of bacteria and cyanobacteria in the kingdom Monera.
• C. Viruses have not been included in this system.
• D. Inclusion of fungi as the third major evolutionary kingdom.

Answer 1

Answer: (C)

Viruses have not been included in this system.

R. H. Whittaker proposed the five kingdom classification. The kingdoms were monera, protists, fungi, plants and animals. The viruses are the obligate parasites which are considered as non-living. They were not placed in any of the five kingdoms which were created by Whittaker. This is considered as the drawback of this system of classification.

Thus, the correct answer is option C.
