The Two-Kingdom system of classification proposed by Linnaeus was found inadequate over time. Which of the following were the primary reasons for its inadequacy? A. It did not distinguish between eukaryotes and prokaryotes. B. It failed to separate unicellular and multicellular organisms. C. It did not differentiate between photosynthetic and non-photosynthetic organisms. D. It grouped organisms primarily based on ph

Step-by-step solution

The Two-Kingdom system of classification proposed by Linnaeus grouped organisms into Plantae and Animalia. It was found inadequate because it did not distinguish between eukaryotes and prokaryotes, unicellular and multicellular organisms, and photosynthetic (green algae) and non-photosynthetic (fungi) organisms. Statement D is incorrect because the Two-Kingdom system was an artificial system and was not based on phylogenetic relationships. Statement E is incorrect because it placed fungi and green plants in the sam
