Talk about asexual reproduction of bryophytes.

Asexual reproduction in Bryophyta (mosses, liverworts and hornworts) may occur by fragmentation or by gemmae. - Fragmentation: Pieces of a gametophyte can break off and form new bryophyte plants. - Gemmae (e.g. Marchantia: class Hepaticopsida) are tiny, multicellular propagules, cup-shaped structures on the gametophytes. Raindrops separate gemmae from the parent plant so they can spread and form new gametophytes.
