Question

Which statement (s) is/are not true for the five-kingdom classification proposed by R.H. Whittaker (1969)?

$\left(a\right)$ The main criteria for classification include cell structure, thallus organization, mode of nutrition, reproductions, and phylogenetic relationship.

$\left(b\right)$ All prokaryotic organisms such as bacteria, blue-green algae, and ferns are grouped together under kingdom Monera.

$\left(c\right)$ Chlamydomonas, Chlorella, and Spirogyra are placed in Algae within plants due to the presence of the cell wall.

$\left(d\right)$ Fungi are placed in a separate kingdom: Kingdom Fungi.

$\left(e\right)$ Paramecium and Amoeba are placed in the animal kingdom due to lack of cell wall.

• A. Only a
• B. a, b and d
• C. a, d and e
• D. a, b and e

Answer 1

Answer: (D)

The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition and reproduction, and phylogenetic relationships. Monera includes bacteria and Ferns are included under Kingdom Plantae, Pteridophytes. Paramecium and Amoeba are placed in Kingdom Protista due to their unicellular nature. Chlamydomonas, Chlorella, and Spirogyra were placed in Algae within plants due to the presence of the cell wall and for their autotrophic nature.
