  • The main principle for analysis by R.H. Whittaker include:
    1. Complexity of cell structure (eukaryotic or prokaryotic)
    2. Body organiazation (unicellular or multicellular)
    3. Thallus organization

          4. Mode of nutrition (autotrophs or heterotrophs)
          5. Reproduction (sexual or asexual)
          6. Phylogenetic relationships

  • And therefore presence or absence of a well-defined nucleus is not the basis for R.H. Whittaker's classification.
