Question

What is the criterion for the classification of organisms as belonging to the kingdom Monera or Protista?

Answer 1

Classification:

1. Classification is the arrangement of organisms in groups.
2. The arrangement is based on their morphology, cellular organization, and evolutionary relationship.
3. R. H. Whittaker postulated five kingdoms, and classifications include Monera, Protista, Fungi, Plantae, and Animalia.

Classification of Monera and Protista:

1. The Monera and Protista are classified according to their cellular organization, mode of nutrition, cell types, and revolutionary relationship.
2. Among the five kingdoms, Monera includes all unicellular prokaryotic organisms which lack a nuclear membrane and are autotrophs. Example: bacteria.
3. Protista is unicellular eukaryotes following both heterotrophic and autotrophic modes of nutrition. Example: Chlorella, Chlamydomonas.
