How is the five-kingdom classification advantageous over the two-kingdom classification?

Solution

The two kingdom classification was proposed by Carolus Linnaeus. The criteria considered for classification were type of nutrition and mobility.
The two kingdoms were Plantae and Animalia.
Plantae are photosynthetic autotrophs and non-motile.
Animals are heterotrophs and motile.

In five kingdom classification, the criteria to classifiy organisms include
1. Presence / absence of cell wall
2. Presence / absence of nuclear envelope
3. Mode of nutrition
4. Mode of reproduction.
5. Body organisation, Unicellular or multicellular
Acoordingly the organisms were grouped in 5 Kingdoms namely,
Monera - Unicellular prokaryotic organisms -Example, Bacteria
Protista - Unicellular eukaryotic organisms - Example, Euglena, Amoeba, Paramoecium etc
Fungi - Eukaryotic, multicellular organisms with saprophytic mode of nutrition.
Example, Rhizopus, Agaricus etc
Plantae - Eukaryotic multicellular organisms, that are photosynthetic autotrophs Example, Mango, Coconut etc
Animalia - Eukaryotic multicellular organisms, heterotrophic in nutrition
Example, Lion, Dog, Monkey etc
Advantages of Five kingdom over two kingdom classification
1. The five kingdom classification seggregates organisms based on five basic criteria, as compared to two kingdom classification where organisms are classified based on two criteria.
2. Unicellular prokaryotes and eukaryotes as well as Fungi were not included in the two kingdom classification.
3. Mixotrophs like Euglena too were not included in the two kingdom classification.
