Liverworts vs. Mosses — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on January 11, 2024
Liverworts are non-vascular plants with a flattened thallus, while mosses are non-vascular but have leafy shoots and stems.

Key Differences
Liverworts and mosses are both bryophytes, yet they exhibit distinct structural characteristics. Liverworts often have a flattened body plan known as a thallus and lack a true stem or leaves. Mosses, however, typically present a more upright stature with distinct, small leaves attached to a stem. While both lack vascular tissue, mosses are more complex structurally compared to the often simpler liverworts.
Reproduction between liverworts and mosses differs as well. Liverworts can reproduce both sexually and asexually, the latter through fragmentation of the thallus or gemmae cups, which house cells that can develop into new plants. Mosses also have both reproductive strategies, but they are known for their elaborate structures that facilitate sexual reproduction, including stalked sporophytes that release spores.
Water dispersion is another area where liverworts and mosses vary. Liverworts are more dependent on a water film for sperm transport during sexual reproduction, which limits them to moist environments. Mosses have adapted to a slightly wider range of habitats by using capillary action to transport water up their stems, although they too favor damp locations.
In terms of habitat, while both liverworts and mosses thrive in moist, shaded environments, liverworts are particularly found in more ephemeral habitats like along streams or temporary ponds, whereas mosses can colonize more diverse and less transient habitats, including tree trunks and rocks.
The ecological roles of liverworts and mosses are also distinct. Liverworts play a role in soil formation and nutrient cycling but are less prominent in ecosystem dynamics compared to mosses, which can be primary colonizers in succession, significantly contributing to the ecosystem by creating habitats for other organisms and storing water.
