Which are the fetal moss plants and what are the mosses

The phylum Bryophytes includes three classes: Liverwosses, Mosses, and Horned Liverworts.

There are many types of mosses, such as cucurbita moss, sphagnum moss, and so on.

The phylum Bryophytes belongs to higher plants. Plants are flowerless, seedless, and reproduce with spores. There are about 23,000 species of bryophytes in the world and about 2,800 species in China.

The phylum Bryophytes includes liverworts, mosses, and horned liverworts. Liverworts contain at least 330 genera and about 8000 species of liverwophytes; Mosses contain nearly 700 genera and about 15,000 species of mosses; There are 4 genera and nearly 100 species of horned liverworts.

There are stems, leaves, no flowers, fruits, seeds, propagated with spores, and in summer sporangia grow on the back of the leaves.

Mosses mostly live on shady and damp ground and shady walls, and generally have stems and leaves. However, there are no ducts in the stems, there are no veins in the leaves, and the roots are very simple and are called pseudoroots. As a result, plants are generally very short.

The leaves of mosses have only one layer of cells, and toxic gases such as carbon dioxide can invade the leaf cells from both the dorsal and ventral sides, threatening the survival of mosses. This characteristic of mosses has been used as an indicator plant to monitor air pollution levels.

There are about 23,000 species of bryophytes worldwide, including hepaticae and musci, bryophytes are generally short and prefer dark, damp environments. However, some people divide bryophytes into three classes: bryophytes, anthocerotae and mosses.

The main characteristics of mosses and mosses are as follows.

Liverworts of gametophytes: mostly flattened phyllodes, dorsal and ventral; There is no vascular tissue in the body; The root is a pseudoroot composed of single cells.

Mosses: There is the differentiation of stems and leaves, and the stem has a central axis, but there is no vascular tissue; The root consists of branched pseudoroots composed of a single row of cells.

Sporophytes: Composed of basal feet, shortened capsule and capsule, the sporophyllum has no capsule, the spore has spores and filaments, and when mature, it is irregularly dehisced at the top.

Moss: It is composed of three parts: basal foot, capsule and spore stalk, the capsule is longer, the top of the capsule has cap and capsule, ** is the capsule, there is a robe in the capsule, there is no elastic filament, and the cover is cracked when it is mature.

Protofilamentous liverworts: Protofilaments are produced when spore capsules, protofilaments are underdeveloped, do not produce bud bodies, and each protofilament only forms a new plant body (gametophyte).

Mosses: The protofilament is well developed, and multiple bud bodies are produced on the protofilament, each bud body forms a new plant body (gametophyte).

Habitat Liverworts: Polyphytes on shady and damp land, rocks and damp tree trunks.

Mosses: Resistant to low temperatures than bryophytes, they can often form large communities in temperate zones, cold zones, alpine tundras, forests, swamps, and often form large communities.

Bryophytes, although they have stems and leaves, do not have distinct roots. Ferns are more talkative than mosses and have distinct roots.

The surface morphology looks:

Liverwosses are generally relatively simple, without the differentiation of roots, stems, and leaves, and their morphology is similar to that of algae.

For example, sphagnum moss does not see the differentiation of roots, stems, and leaves.

Mosses are relatively advanced, with false roots and differentiation similar to stems and leaves, and simple conduction tissues. However, there are no vascular bundles, and the distance between the water and nutrient transport is very limited, so the stature is short, and the height is generally not more than l0 cm.

For example, the lycopodium is an ancient and primitive fern. It has real roots, stems, and leaves. Whether it is the upward branch or the downward root, the cherry blossoms are all divided at the top.

The main annihilation characteristics of the Liverworts and Mosses are the origin beams.

The growth of mosses also needs sunlight, but the light intensity requirements are lower, and it is the fungi that really do not need sunlight.

Mushrooms or reishi, dog urine moss can also grow.

No, all of them need the sun.

No, but you can see less light.

I suggest you read "Journey to the Center of the Earth".

Jules Verne's.

It should be quite similar to what you want it to be.
