Main characteristics of algae, mosses and ferns
Algae belong to a class of lower organisms, with simple structure, rootless, differentiated stems and leaves, usually single-celled, colony or multicellular bacteria. Algae plants are rich in light and pigments, such as chlorophyll, which can carry out full photosynthesis and belong to autotrophs.
Bryophytes have large root leaflets, and some species only have stems, which are suitable for living in a humid and semi-cool environment. Pteridophytes are a group of spore plants with a high level of evolution. They develop directly from spores into whole plants without seeds.
Algae, bryophytes and ferns are the main representative plants and their distribution.
The representative algae plants are cyanobacteria, dinoflagellate, Chlorella, chrysanthemum, kelp and laver, which are often eaten in life. The representative bryophytes are cucurbitaceae, liverworts and sphagnum. Pteridophytes include Selaginella, Dictyophora, Nephropteris, etc.
Algae plants are relatively low and closest to primitive plants. They mainly live in water, but also live on the surface or inside of wet rocks, trunks and soil. Bryophytes live in a humid and semi-cool environment, while ferns grow in tropical or subtropical regions, mainly living in soil.
