Bryophyte is a traditional name used to refer to all embryophytes (land plants) that are "non-vascular plants", such as mosses, hornworts, and liverworts. The defining feature of bryophytes is that they do not have true vascular tissue. Although some do have specialized tissues for the transport of water, they are not considered to be true vascular tissue since they do not contain lignin. As of 2014, it is uncertain whether bryophytes are a natural or monophyletic group or a paraphyletic group, but the name is convenient and remains in use as a collective term for mosses, hornworts, and liverworts. Bryophytes produce enclosed reproductive structures (gametangia and sporangia), but they produce neither flowers nor seeds, reproducing via spores. The term "bryophyte" comes from Greek βρύον, bryon, "tree-moss, oyster-green" + φυτόν – phyton "plant".Whitout photomaker program.
