Marchantia reproduces asexually in two ways –
- By small clumps of tissues known as gemmae. These are produced in small gemmae cups forming on the upper surface of the thallus. When it matures, raindrops can break it free of the cup and disperse them away from the thallus. It can develop into a gametophyte plant through mitosis of gemma lands on a proper substrate.
- By fragmentation when the older portions of the thallus die which separate younger parts which then develop as distinct individuals
