Question

Which of the following can be considered as a disadvantage in Five Kingdom Classification?

• A. Prokaryotes got a separate place as Kingdom Monera
• B. Shows phylogenetic relationship
• C. Chlorella and Chlamydomonas (autotrophic) placed with Paramecium and Amoeba (heterotrophic) in Kingdom Protista
• D. None of the above

Answer 1

The correct option is C Chlorella and Chlamydomonas (autotrophic) placed with Paramecium and Amoeba (heterotrophic) in Kingdom Protista

In order to develop phylogenetic classification, R.H Whittaker in 1969 divided all organisms into five kingdoms: Monera, Protista, Fungi, Plantae and Animalia. This system ensured placement of prokaryotes in a separate kingdom Monera because prokaryotes differ from other organisms in their genetic, cellular organisation. A perceivable disadvantage in this type of classification is the kingdom Protista where organisms like Chlorella and Chlamydomonas (autotrophic) placed with Paramecium and Amoeba (heterotrophic) are placed together. The kingdom Protista contains Chlaymydomonas, chlorella which were earlier placed in Plant kingdoms into Protista. The kingdom Protista contains photosynthetic members, consumer decomposer members, and protozoans.
