Bryophytes

Bryophytes (liverworts, mosses, and hornworts) are non-vascular plants that appeared on earth over 450 million years ago.

Liverworts and hornworts are both bryophytes, but aspects of their structures and development are different.

Mosses are bryophytes that live in many environments and are characterized by their short flat leaves, root-like rhizoids, and peristomes.
