 3629  180 Biological Classification Report Error

Solution:

Two kingdom classification (founded by Linnaeus) worked well for a long time. But this system did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organisms, photosyntheticand non-photosynthetic organisms. Although, classification of organisms (into plants and animals) was easily done and was easy to understand, but a large number of organisms did not fall into either category. Hence, the two kingdom classification used for a long time was found inadequate.
