The gametophyte bears organs for sexual reproduction. Compare and contrast vascular and non-vascular plant reproduction. The sporophyte remains attached to the gametophyte much like a parasite, dependent for food and water on the gametophyte, and divides by mitosis. Mosses are flowerless small plants found under the division Bryophyta along with liverworts and hornworts. Late in the summer, the calyptra and operculum become detached from the sporangium allowing the spores to be released. These swim down the canal in the archegonium to the chamber containing the egg.
