Taxonomy is the procedure for ranking plants.
Step-by-step explanation:
The plants are ranked depending upon the resemblances and differences it has from another kind of plants. They can be ranked depending upon their leaves, roots, stems and other structures. They are defined into more general categories depending on the similar traits in the same group.
The plants are broadly classified into vascular and non vascular .Example, a flowering plant is a higher green plant and based on its gross structure does lie in the kingdom of Plantae, not in fungus or bacteria.
