Bryophytes are represented by three phyla of small herbaceous plants: liverworts,
hornworts, and mosses. They do not flower or produce seeds, but rather reproduce through spores. All bryophytes are nonvascular,
ecologically persistent, and they never form xylem tissue. The photosynthetic phase of the life cycle of bryophytes is the
haploid, gametophyte generation, rather than the typical diploid sporophyte generation that is seen in many other life cycles.
Because bryophytes are nonvascular, they need water to survive and one of the most popular examples of this is mosses.
