Drawback of two-kingdom classification

In the two-kingdom classification following are drawbacks

• The plants comprised of photosynthetic and non-photosynthetic species.
• Fungi, that feed on dead organic matter, were placed under photosynthetic plants.
• There was another class of classification needed were the organisms with the same characteristics were clubbed into one kingdom.
• This system did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organisms and photosynthetic (green algae) and non-photosynthetic (fungi) organisms.
• There are some organisms which neither fall into plant nor animal kingdom like Lichens.
