Its distribution is confined to geothermal areas. Liverworts Marchantiophyta are either made up of a thallus or leafy stems; unlike many mosses, liverwort leaves do not have ribs costas.
Around liverwort species have been found here to date. Mosses Bryophyta have thin stems around which simple leaves branch out.
Moss leaves frequently have a midrib. A total of moss species have been found in Iceland. Back to top. Please tell us why: There is not enough content. It has a large number of green tissues. In mosses, branching of leaves is lateral and extra-axillary. In it, amphigastria or scales are usually absent. Due to a large number of green tissues in the sporangium, it makes it semi-independent. In mosses, seta grows very slowly and fully develops into mature spores.
Elaters are generally absent in mosses. In it, the peristome teeth are usually present in the apical region of capsule. Sterile columella usually presents in the capsule of mosses. In mosses, a branched and branched protonema is present. In mosses, chlorophyll and stomata are generally present in sporophyte for the gaseous exchange.
In mosses, a capsule is regular and sex organs usually develop from the superficial cells that are present at the apex of the leafy gametophyte. In mosses, the gametophyte is the main plant body, which is branched and thalloid protonema. The above discussion concludes that liverworts and mosses are the non-vascular plants. Liverworts are the plants in which gametophyte is thallose or foliose, whereas the mosses are the plants in which gametophyte is a prostate.

Peristome teeth are absent. Peristome teeth are present in the apical region within the capsule. The columella is absent. Sterile columella is present in capsule.
Protonemata is absent in liverworts. Mosses have filamentous protonemata. Chlorophyll and stomata are absent. Chlorophyll and stomata are present for gaseous exchange in the sporophyte. Sex organs are present on the dorsal side of the thallus, that grow from the superficial cells.
Sex organs grow at the apex of the leafy gametophyte from the superficial cells. Unlike the other plants, liverworts differ from the typical plant by having a single layer of the cells. They also vary by not having stomata, which has the use of gaseous exchange for the process of photosynthesis in the advanced plant.
Liverworts can be leafy or thalloid, and the first one is the simple form of the species by the latter one has the complexity as they have multiple thick layers of green tissues known as thallus. Liverworts are the flattened plants that grow across the upper layer of soil, mountains, rocks and on the other plants. The dominating phase is the gametophyte, while the sporophyte phase occurs for a short duration. Instead of the roots, liverworts have rhizoids, which are hair-like structure and support the plant in anchorage to the surface, and in absorbing water.
So, liverworts have two parts the upperside and upper. First one is for photosynthesis, and so it is green in colour, while the second part consists of the rhizoids. The plant reproduces by using spores, for the fertilization process, the sperm travel through water or wind to the egg of the other plant. The fertilized eggs develop into spores and get dispersed. Likewise the liverworts, Mosses also have rhizoids and reproduce by spores.
Mosses are present in wet environments like alpine, rainforest and wetland s. These can be commonly seen in wet areas and grow their colonies on sidewalks, brick walls, driveways and other human-made structure. Their favourable condition to grow is the wet climate. The gametophyte containing sperms cells are covered by the thin layer of water, travel to another gametophyte for fertilization with eggs.
The fertilized egg will grow into a sporophyte, which will later develop into spores. Therefore, it is said that the gametophyte generation is longer and dominant over the sporophytic generation and develops on the nutrition and water provided by the gametophytes.
In this article, we came to know about the non-vascular plants which are liverworts and mosses, on which points they differ and how are they similar.
