Bryophyta

Bryophyta are called the amphibians of the plant kingdom. The plant body is commonly differentiated to form stem and leaf like structures. However, there is no specialized tissue for conduction of water and other substances from one part of the plant body to the other. Bryophyte is a traditional name used to refer to all embryophytes (land plants) that do not have true vascular tissue and are therefore called 'non-vascular plants'.Some bryophytes do have specialized tissues for the transport of water; however since these do not contain lignin, they are not considered to be true vascular tissue. Currently bryophytes are thought not to be a natural or monophyletic group; however the name is convenient and remains in use as a collective term. 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 - fyton "plant".
