*A distinction between unicellular and multi cellular organisms is not possible in case of algae in this system of classification.
*Each group has so many diversities that it is difficult to keep them together. For example, monera and Protista contain both walled and wall-less organisms. Photosynthetic and non-photosynthetic organisms, cellular or filamentous organism.
*Virus has not been included in this kingdom.
*Archaebacteria differ from other bacteria in structure, composition and physiology.
*Mycoplasma are quite different form bacteria where they have been placed along with prokaryotes.
