Question

Mention the short coming of two kingdom classification?

Answer 1

The explanation is as follows.

Two Kingdoms classification has many shortcomings. Some are as follows:

1. In two kingdom classification, unicellular organism are put together with multicellular organism.
2. Two kingdom classification has put together eukaryotes (organism with true nucleus in their cells), with prokaryotes (organism without true nucleus).
3. Two kingdom classification has put together autotrophs and heterotrophs, such as non -photo synthesizing fungi with photosynthetic green plants.
4. Two kingdom classification has little regard for diversified form.
5. Lichens is a peculiar group of dual organisms which are formed by an association between an algae and fungus. They have neither plant character not any animal character.
6. Group of unicellular algae (e.g. euglenoids, diatoms and dianoflagellates) and protozoa show sufficient degree of resemblance.

Two kingdoms classification was an artificial system of classification. This division was based only on morphological appearance. So, two kingdom classification was rejected by the scientist. The most accepted classification is five kingdom classification proposed by R.H. Whittaker.
