Five kingdom system of classification suggested by R.H. Whittaker is not based on

  1. presence or absence of a well defined nucleus
  2. mode of reproduction
  3. mode of nutrition
  4. complexity of body organisation.

Answer

(1) presence or absence of a well defined nucleus

Solution

As per NCERT, the main criteria used by R.H. Whittaker (1969) for the five kingdom classification were cell structure, body organisation (thallus organisation), mode of nutrition, reproduction and phylogenetic relationships.

∴ Mode of reproduction, mode of nutrition and complexity of body organisation are all criteria of the system.

⇒ Presence or absence of a well defined nucleus is not listed as a separate criterion of the five kingdom system; it is the basis of the prokaryotic–eukaryotic distinction used earlier.
