Bryophytes are non-vascular land plants that reproduce via spores and include mosses, hornworts and liverworts. They produce enclosed reproductive structures but no flowers or seeds. Pteridophytes, also known as vascular cryptogams, reproduce and disperse via spores and include ferns, horsetails, clubmosses and quillworts. However, ferns and horsetails are more closely related to seed plants than lycophytes. So pteridophytes do not represent a true taxonomic group but the term is still used informally.

4.  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".[1] 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.As of 2014, it is uncertain whether bryophytes are a natural
ormonophyletic 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 norseeds, reproducing via spores.
The term "bryophyte" comes from Greek βρύον, bryon, "tree-moss, oyster-green"
+ φυτόν – phyton"plant".

5. Pteridophytes or Pteridophyta, in the broad interpretation of the term ,
are vascular plants (plants with xylem and phloem) that reproduce
and disperse via spores. Because they produce neither flowers nor seeds,
they are referred to as cryptogams. The group
includes ferns, horsetails, clubmosses, spikemosses and quillworts. These do
not form a monophyletic group, because ferns and horsetails are more
closely related to seed plants than to lycophytes (clubmosses, spikemosses
and quillworts). Therefore, pteridophytes are no longer considered to form
a valid taxon, but the term is still used as an informal way to refer to ferns
(monilophytes) andlycophytes, and some recent authors have used the
term to refer strictly to the monilophytes
