Question

Drawbacks of Two Kingdom Classification in detail

Answer 1

****Heyy friend here is ur answer****
Drawbacks of 2 kindom classification are as follows:-
1) Both Eukaryotes and prokaryotes were placed together.
2) In plant knigdom there were species which were photosynthetic and non photosynthetic, so there were also placed together.
3) There were some animals which show both animals as well as plants character, so no fixed position was there for them. 
E.g. Euglena

Hope it was helpful:-)

Answer 2

Prokaryotes and eukaryotes were put together.

Fungi which are non photosynthetic and live by decomposing and absorbing organic matter were clubbed together with photosynthetic green plants.

Lichens were living organisms but grow on rocks and can be mistaken as non living objects.

Bacteria could not be classified as plants or animals.
