Question
Write down two disadvantages of two kingdom classification.
✓
Answer
The two kingdom system of classification was not found to be suitable to many scientists due to large diversity among the organisms and many other limitations.
The main demerits of the system are:
- Many protozoans possess characters of both plants and animals. For example, Euglena has animal characters but it contains chlorophyll.
- Bacteria and Cyanobacteria (blue-green algae) have many similarities between them and are quite different from other organisms. Thus, it is difficult to place them in their plant or animal kingdom.
