The plant kingdom can also be classified on the basis of the presence or absence of conductive (vascular) tissue.

Ferns (pteridophytes), gymnosperms and angiosperms have vascular tissue which transports the nutrients and water through the plant. They are collectively known as tracheophytes.

Mosses, liverworts, hornworts (bryophytes) are non-vascular i.e. they do not have conductive tissue to transport sugar, water and nutrients.
