Necessity and significance of classification
The following are importance of classification
- Classification makes the study of living things easy
- Classification makes communication easy among biologists from different parts of the world
- It provides good organized system in which a newly identified organism can be easily fitted in future.
- It makes it easier to identify organisms
- It can be used to predict characteristics that are present in the members of the same group.
Major units of classification: (naming)
The major groups of living things are the kingdoms. Previously, living things were categorized into two main groups; plantae and animalia kingdom. But this classification caused difficulties since some organisms seemed to posses some of the characteristics of both groups. For example, euglena is capable of feeding like an animal and locomote like an animal. Therefore, it is placed in animalia kingdom. But the same euglena has chlorophyll and it is capable of manufacturing its own food. Therefore, it should also be placed in plantae kingdom. Such an organism does not seem to fit exactly in animalia or plantae kingdom. Thus, euglenas are assigned in the major group of their own.Currently, there are five major groups (kingdoms) of living things.
Kingdoms: Monera, protoctista,fungi,plantae, animalia (At least one example of each)
