Two-kingdom to five-kingdom classification MCQs with solutions
10 of the 13 published questions on this topic, exactly as they appear in a test. Answers and worked solutions come with your result rather than on this page.
Who proposed the five-kingdom system of classification?
- A. R.H. Whittaker
- B. Carolus Linnaeus
- C. Ernst Haeckel
- D. Carl Woese
Which kingdom in Whittaker's five-kingdom system contains prokaryotic organisms?
- A. Protista
- B. Monera
- C. Fungi
- D. Plantae
Why was the traditional two-kingdom system inadequate for classifying organisms such as bacteria and fungi?
- A. It did not clearly separate prokaryotes from eukaryotes or fungi from plants
- B. It contained too many kingdoms for practical use
- C. It excluded all multicellular organisms
- D. It classified organisms only by geographic distribution
Which criterion most directly separates Monera from Protista in the five-kingdom system?
- A. Presence or absence of a true nucleus
- B. Mode of locomotion
- C. Ability to reproduce
- D. Habitat in water
A major limitation of the old two-kingdom system was that it
- A. did not adequately separate prokaryotes, fungi and many unicellular organisms
- B. already distinguished all major cell types correctly
- C. classified organisms only by DNA sequence
- D. included five kingdoms from the start
An unknown organism is unicellular, has a membrane-bound nucleus and obtains nutrition by absorption. Which kingdom-level placement is more consistent with Whittaker's criteria than Monera?
- A. Protista
- B. Monera
- C. Animalia
- D. Plantae
A classifier wants to separate organisms that ingest food from organisms that absorb dissolved organic matter after extracellular digestion. Which pair of kingdoms is most directly distinguished by this nutritional difference?
- A. Animalia and Fungi
- B. Plantae and Monera
- C. Protista and Plantae
- D. Monera and Animalia
An organism is unicellular, prokaryotic and lacks a membrane-bound nucleus. In Whittaker's five-kingdom system it belongs to
- A. Monera
- B. Protista
- C. Fungi
- D. Animalia
A unicellular eukaryote with a membrane-bound nucleus but no multicellular tissue organisation is most naturally placed in
- A. Protista
- B. Monera
- C. Animalia only
- D. Plantae only
Two organisms are both multicellular and eukaryotic. One is photosynthetic with cellulose walls, while the other is heterotrophic with chitinous walls and absorptive nutrition. Which classification follows?
- A. The first is Plantae and the second is Fungi
- B. Both belong to Plantae
- C. Both belong to Fungi
- D. The first is Protista and the second is Animalia
Common mistakes in Two-kingdom to five-kingdom classification
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Assumes all walled organisms are plants.
- Reduces classification to one superficial character.
- Classifies organisms using only unicellularity or presence of a cell wall.
