In five kingdom system, the main basis of classification is [2002]a)st...
The five-kingdom system of classification is based on the mode of nutrition of organisms. This system was proposed by Robert Whittaker in 1969. The five kingdoms are:
1. Monera
2. Protista
3. Fungi
4. Plantae
5. Animalia
Explanation:
Mode of Nutrition refers to the way in which an organism obtains its food. Based on this, the five-kingdom system of classification is as follows:
1. Monera: These are unicellular organisms that lack a nucleus. They obtain their nutrition through various modes such as photosynthesis, chemosynthesis, or absorption.
2. Protista: These are unicellular or multicellular organisms that have a nucleus. They obtain their nutrition through various modes such as photosynthesis, ingestion, or absorption.
3. Fungi: These are multicellular organisms that have a cell wall made up of chitin. They obtain their nutrition through absorption.
4. Plantae: These are multicellular organisms that have a cell wall made up of cellulose. They obtain their nutrition through photosynthesis.
5. Animalia: These are multicellular organisms that lack a cell wall. They obtain their nutrition through ingestion.
Conclusion:
Thus, the mode of nutrition is the main basis of classification in the five-kingdom system. This system is widely used in biology to classify organisms based on their characteristics and evolutionary relationships.
