Explanation:
Whittaker's five kingdom system of classification is based on five criteria:
1. Mode of nutrition: The way in which an organism obtains its food.
2. Complexity of body organization: The level of organization of cells, tissues, and organs.
3. Cell structure: The presence or absence of a well-defined nucleus.
4. Mode of reproduction: The way in which an organism reproduces.
5. Habitat: The environment in which an organism lives.
Out of these five criteria, the five kingdom system of classification suggested by R.H. Whittaker is not based on the presence or absence of a well-defined nucleus. The five kingdoms are:
1. Monera: Prokaryotic organisms that lack a well-defined nucleus.
2. Protista: Eukaryotic organisms that have a well-defined nucleus and are unicellular or simple multicellular.
3. Fungi: Eukaryotic organisms that have a well-defined nucleus and are heterotrophic.
4. Plantae: Eukaryotic organisms that have a well-defined nucleus and are autotrophic.
5. Animalia: Eukaryotic organisms that have a well-defined nucleus and are heterotrophic.
Thus, the mode of nutrition, complexity of body organization, mode of reproduction, and habitat are the criteria that determine the classification of organisms into the five kingdoms.
