Bryophytes are non-vascular plants that include liverworts, hornworts and mosses. They can reproduce sexually through diplohaplontic life cycle. Bryophytes have heteromorphic: gametophytes are the dominant forms, while sporophytes are dependent on gametophytes for their development. They can be either monoecious (have both male and female gametophytes on the same plant) or dioecious (male and female gametophytes are on different plants).
In addition to sexual reproduction, liverworts can also reproduce asexually through fragmentation and gemmae.

These gemma cups are filled with gemmae which can develop into a new plant under proper conditions.

Mosses: there are more than 9500 species of mosses. Sphagnum moss in a bog is one of them.
