The characteristics used to classify plants is different from animals because the basic design are different, based on the need to make their own food (plants) or acquire food (animals).

Criteria for deciding divisions in plants are :

Differentiated/ Undifferentiated plant body

Presence/ absence of vascular tissues

With/without seeds

Naked seeds/ seeds inside fruits

But the animals can't be divided into groups on these criteria. It is because the basic designs of animals are very different from plants. They are divided on the basis of their body structure.
