What are angiosperms, gymnosperms, ferns, mosses and algae? Seek an answer

Most of the flowering plants we see in our daily life are angiosperms, such as cereals, beans, potatoes, fruits and vegetables for our consumption. Angiosperms include: Lily, Populus euphratica, Pterocarya stenoptera, Populus davidiana, Salix matsudana, Salix weeping, Betula platyphylla, Ulmus pumila, Mulberry, Ficus carica, Magnolia grandiflora, Michelia, Liriodendron chinense, Nandina domestica, Peony, Camellia sinensis, Platanus orientalis and Crataegus pinnatifida. Citrus, Ailanthus altissima, Toona sinensis, Melia azedarach, Acer truncatum, Ilex japonicum, Buxus macrophylla, Buxus macrophylla, Jujube, Grape, Hibiscus, Lagerstroemia indica, Pomegranate, Red Ruimu, Davidia involucrata, Rhododendron, Honeysuckle, Persimmon, Forsythia, Yingchun and Lilac. Gymnosperms are primitive seed plants with a long history of development. Many gymnosperms are important trees, especially in the northern hemisphere, where more than 80% of the forests are gymnosperms: larch, fir, Pinus armandii, spruce, cycad, Casuarina equisetifolia, maize, Chinese cymbidium, Metasequoia glyptostroboides, Pinus massoniana, Pinus tabulaeformis, Cedar, fir, Ginkgo biloba, Taxus chinensis, Taxodium, Taxodium, Taxodium, Taxodium and Taxodium. Ferns have developed sporophytes, which are divided into roots, stems and leaves, and have no flowers. They reproduce by spores with obvious alternation of generations, and asexual generations are dominant. Pteridophytes include: fern, Adiantum, Pteris formosana, Cervus elaphus, Alsophila spinulosa, pteridophyte, Selaginella, Cuiyuncao, Osmunda japonica, Boston fern, pteridophyte, Pteridophyte, petrified pheasant's tail, sickle fern, rib fern, fishtail fern, Lisa fern and palm fern. Bryophytes are green autotrophic terrestrial plants, and plants are gametophytes, which germinate from spores into protonema and then develop from protonema. Bryophytes are generally small, and the plants (gametophytes) that are usually seen can be roughly divided into two types: one is liverworts, which keep the shape of leaflike bodies; The other is moss, which begins to differentiate like stems and leaves. Bryophytes have no true roots, only pseudoroots (filaments composed of single cells or a series of cells with epidermal processes), which play a supporting and fixing role. The differentiation level of tissue in stem is not high, only the differentiation of bark and axis, and there is no real vascular bundle structure Leaves are mostly composed of a layer of cells, which can not only carry out photosynthesis, but also directly absorb water and nutrients. They are also the oldest plants. Bryophytes include: cucurbitaceae, liverworts, moss, foot moss, sphagnum moss, black moss and other algae plants, including several different kinds of organisms that generate energy through photosynthesis. Generally speaking, they are simple plants, and some algae are related to higher plants. Although other algae seem to obtain photosynthetic capacity from cyanobacteria, they have independent branches in evolution. All algae lack real roots, stems, leaves and other tissue structures that can be found in higher plants. The difference between algae and bacteria and protozoa is that the way algae produce energy is photosynthetic autonomy.
