Which of the following best describes the limitation of the Two Kingdom system of classification?
Options
- AIt only classifies multicellular organisms
- BIt only classifies photosynthetic organisms
- CIt does not distinguish between eukaryotes and prokaryotes, unicellular and multicellular organisms, and photosynthetic and non-photosynthetic organisms
- DIt only classifies non-photosynthetic organisms
Correct answer
C. It does not distinguish between eukaryotes and prokaryotes, unicellular and multicellular organisms, and photosynthetic and non-photosynthetic organisms
Step-by-step solution
In Linnaeus' time a Two Kingdom system of classification withPlantae and Animalia kingdoms was developed that included allplants and animals respectively. This system did not distinguish betweenthe eukaryotes and prokaryotes, unicellular and multicellular organismsand photosynthetic (green algae) and non-photosynthetic (fungi)organisms. Classification of organisms into plants and animals was easilydone and was easy to understand, but, a large number of organismsdid not fall into either category. Hence the two kingdom classificationused for a long time was found inadequate. Besides, gross morphologya need was also felt for including other characteristics like cell structure,nature of wall, mode of nutrition, habitat, methods of reproduction,evolutionary relationships, etc.
