							Dear Student

In plants body basic structure is a major criteria based on which Thallophytes are different from Bryophytes. Apart from this absence or presence of seeds is another important criteria. Gymnosperms and angiosperms are further segregated based on if seeds are covered or not.

It is clear that it is the morphological character which makes the basis for classification of plants. In animals classification is based on more minute stnictural variations. So in place of morphology, cytology forms the basis.

Animals are classified based on layers of cells, presence or absence of coelom. Further higher the hierarchy animals are classified based on presence or absence of smaller features, like presence or absence of four legs.
