Difference between liverworts and mosses

Main difference

The main difference between liverworts and mosses is that liverworts have a gametophyte which is a foliose or a talosa, while mosses have a gametophyte which is a prostate, branched filamentous structure.

Agrimony against mosses

Liverworts have a gametophyte that is foliose or talosa, while mosses have a gametophyte that is a branching filamentous prostate. Liverworts are non-vascular plants consisting of leafy stems or lobes, while mosses are non-vascular plants consisting of leafy stems. Liverworts fit into the Marchantiophyta division, while mosses fit into the Bryophyta division.

Liverworts are dorsoventral and radial, while mosses are the only radial. Liverworts consist of unicellular rhizoids, while mosses consist of multicellular rhizoids. Liverworts produce a protoneme that is reduced, while mosses produce a protoneme that is prominent.

In liverworts, the leafy structures are arranged in two or three rows in a flattened pattern, while in mosses, the leafy structures are arranged in a spiral or whorl. In liverworts, the sporangium has a small amount of green tissue, while in mosses, the sporangium has an adequate amount of green tissue.

Liverworts have leaves without midrib, while mosses have midrib leaves. In liverworts, the branching is usually dichotomous, while in mosses, the branching is usually lateral and extra-axillary. In liverworts the capsule generally has elaters, while in mosses the elaters are generally absent. In liverworts, the peristomal teeth are absent, while in mosses they are.

What are liverworts?

Liverworts are non-vascular plants in which the gametophyte is foliose or talosa. Liverworts are plants with a conscious and independent gametophyte, consisting of leafy stems or lobes. Liverworts are classified as the Marchantiophyta division placed under the Bryophyta phylum. Liverworts consist of a single layer of cells in their leaves.

Liverworts generally grow by spreading on rocks, soil, and other plants. The sheet-like structure is rolled into two or three rows of flattened pattern. The sporophyte is conspicuous and depends on the gametophyte. It has roots as unicellular rhizoids that intervene in the uptake of water and is used for fixation to the substrate.

It has sporangia that has a small amount of green tissue. Peristomic teeth are also absent in liverworts. Elaters are present in liverworts. In liverworts, the protonema is greatly reduced and completely absent.

Liverworts have radial or dorsiventral symmetry. In liverworts, the leaves generally do not have a midrib. In him, the branching is usually dichotomous. In it, the plants can have anfigastria or scales. In it, the mushroom fully develops into mature spores. In it, the capsule usually has elaters.

In liverworts, the columella is usually absent. Liverworts generally grow in a shady, humid or humid location. Asexual reproduction takes place in liverworts by thallus fragmentation. In liverworts, gammae is found in the thallus as asexual buds.

Examples

Riccia, Marchantia and Porella, etc.

What are mosses?

Mosses are non-vascular plants in which the gametophyte is a prostate. Mosses are plants with prominent, conscious, and independent gametophytes that have leaf-like stems. Mosses are classified in the phylum Bryophyta as the division Bryophyta.

It has root-shaped rhizoids that participate in the uptake of water and the absorption of water from the soil. In it, the leaves have a midrib. Its rhizoids are multicellular. Mosses have radial symmetry. It has a large number of green tissues.

In mosses, the branching of the leaves is lateral and extra-axillary. In him, the anfigastria or the scales are usually absent. Due to a large number of green tissues in the sporangium, it makes it semi-independent. In mosses, the mushroom grows very slowly and completely turns into mature spores.

Elaters are generally absent in mosses. In it, the peristomal teeth are usually present in the apical region of the capsule. The sterile columella usually occurs in the capsule of the mosses. In mosses, a branched and branched protoneme is present. In mosses, chlorophyll and stomata are generally present in the sporophyte for gas exchange.

In mosses, a capsule is regular and the sex organs generally develop from the superficial cells that are present at the apex of the leafy gametophyte. In mosses, the gametophyte is the main body of the plant, which is branched protoneme and stem.

Examples

Funaria, Polytricum and Sphagnum, etc.

Key differences

  1. Liverworts have a gametophyte that is foliose or talosa, while mosses have a gametophyte that is a branching filamentous prostate.
  2. Liverworts produce a protoneme that is reduced, while mosses produce a protoneme that is prominent.
  3. Liverworts have leaves without midrib, while mosses have midrib leaves.
  4. In liverworts, the sporangium has a small amount of green tissue, while in mosses, the sporangium has an adequate amount of green tissue.
  5. In liverworts the capsule generally has elaters, while in mosses the elaters are generally absent.
  6. Liverworts are dorsoventral and radial, while mosses are the only radial.
  7. In liverworts, the leafy structures are arranged in two or three rows in a flattened pattern, while in mosses, the leafy structures are arranged in a spiral or whorl.
  8. Liverworts consist of rhizoids that are unicellular, while mosses consist of rhizoids that are multicellular.

Final Thought

The above discussion concludes that liverworts and mosses are non-vascular plants. Liverworts are the plants in which the gametophyte is thallose or foliose, while the mosses are the plants in which the gametophyte is a prostate.
