Question

on what basis are the plants and animals put into different categories​

Answer 1

Plants and animals are put into different categories on the
basis of Mode of nutrition. Plants are autotrophs, while animals are heterotrophs. Cell wall is present in
plant cells, while it is absent in
animal cells. Also, locomotion, absence of chloroplasts etc. make them different .

☆$\red {HELLO\:DEAR}$☆

Plants and animals differ in many features such as the absence of chloroplasts, presence of cell wall, etc. But, locomotion is considered as the characteristic feature that separates animals from plants.

This is because the absence of locomotion in plants gave rise to many structural changes such as the presence of a cell wall (for protection), the presence of chloroplasts (for photosynthesis) etc.

Hence, locomotion is considered to be the basic characteristic as further differences arose because of this characteristic feature.
