Asked by dharmendra | 13 Sep, 2021, 09:26: AM
Expert Answer
Whitakker’s method of classification has the following merits:
- Unicellular and multicellular organisms are kept and categorized separately.
- Fungi is a separate kingdom because of its mode of nutrition.
- Autotrophic and heterotrophic modes of nutrition are placed in distinct groups.
- Prokaryotes are unicellular organisms which are placed in Kingdom Monera.
- It is more naturally segregated than classified under two kingdoms.
Whitakker’s method of classification has the following demerits:
- Unicellular algae are kept in kingdom Protista, whereas algae like multicelluar organisms are ketp in kingdom Plantae. But similar organisms must be put together.
- There is diversity in kingdom Protista. Dissimilar organisms must not be kept in same group.
- All organisms other than moneran shows that they are polyphyletic in origin. It is a great shortcoming of five kingdom classification.
- There is no place for viruses in five kingdom classification.
- Similar organisms are kept far from each other. For example, unicellular and multi cellular algae.
