Which of the following does not form the basis of five kingdom classification?
- A. Body organization
- B. Cell structure
- C. Mode of nutrition
- D. Mode of excretion
Answer: D. Mode of excretion
- The five-kingdom classification system, proposed by Robert Whittaker in 1969, primarily focuses on four key characteristics to categorize organisms into five distinct kingdoms:
- Cell structure (prokaryotic or eukaryotic)
- Cell type (unicellular or multicellular)
- Nutrient acquisition (photosynthesis, chemosynthesis, or heterotrophy)
- Body organization (absence or presence of true tissues and organs)
- As you can see, mode of excretion is not explicitly considered as a primary basis for classification in this system. While some kingdoms may have specific modes of excretion, it’s not a defining feature for grouping organisms together.
The five kingdoms are:
- Monera
- Protista
- Fungi
- Plantae
- Animalia
