moss plant door plants are small and generally only a few centimeters high. Born in a wet environment. Although there is root, stem, leaf differentiation, but its root is composed of single-cell or multi-cell false root, stem and leaf differentiation is obvious, but only the differentiation of the infusion cells, and no support tube bundle and middle column. The matching children have the advantage in the life cycle. The plants of the sexual generation are called ligands, which are the plants we see with false roots, stems, and leaves. An egg collector or sperm collector is formed on the lithosome, a female match (egg) is produced in the sperm collector, and a male match (sperm) is produced in the sperm sequestrator, and the sperm has whiplash and can swim in the water. Because the plants of this period produced matchtons, the plants were called matchtons, and this generation was sexual.
asexual generation of spores are developed from fertilized eggs through the embryo. Spores are composed of spores ,handles and feet, which are extended into the lithosome to absorb nutrients, and thehandle connects the foot with the spores which are partially divided by the spores and formed by a common division. Because asexual plants produce spores, they are called spores. Spores germinate into primary silk in human soil and then grow into new ligations.
this phenomenon of sexual and asexual generational rotation is called intergenerational rotation. Moss plant ligands have false roots, stems, leaf differentiation, can camp independent life, life period is also long, and spore parasites in the matching body, life period is short, so moss plants are the dominant matching body. In this case, the growth and flossing on land is much worse than that of ferns and seed plants where spores dominate.
moss plants are currently available for medicinal purposes. Land money Marchantia po1ymorpha Linn. , whole grass can clear the heat detoxification, anti-swelling pain, raw muscle hemostation, large leaf rhhodbryum roseum Limp., whole grass can calm down, cure panic, palpitations, heart disease and nerve weakness. 。
