The major divisions of Plantae and the basis for these divisions are as follows:
Thallophyta: Simple body design; with no differentiation into root, stem and leaves.
Bryophyta: Body is differentiated into stem and leaf-like structures. Vascular system is absent.
Pteridophyta: Body is differentiated into root, stem and leaves. Vascular system is present.
Reproductive organs are inconspicuous. Seeds are not produced.
Gymnosperms: Seeds are naked.
Angiosperms: Seeds are covered.

The first level of classification among plants depends on whether the plant body has well differentiated, distinct components. The next level of classification is based on whether the differentiated plant body has special tissues for the transport of water and other substances within it. Further classification looks at the ability’ to bear seeds and whether the seeds are enclosed within fruits.
