Algae ferns Are bryophytes herbaceous

Algae certainly not, because it mostly lives in water, and there is no stem differentiation Usually herbaceous plants and woody plants are divided into whether the xylem in the stem is developed, the stem of herbaceous plants is softer, the xylem is underdeveloped, bryophytes have stem and leaf differentiation, but there is no vascular tissue, it lives on land, it is relatively short, it should be herbaceous, ferns have vascular tissue, most vascular tissues are underdeveloped, there are underground transverse rhizomes or aerial ones, so most ferns are herbaceous plants, but there are also vascular tissues that form a column Woody plants that resemble trees such as alders.

Algae are not, because the division of herbaceous plants and woody plants is to see if the xylem in the stem is developed herbaceous plants have less developed stems than softer xylem .

Mosses are, and so are ferns.

Herb is a general term for a class of plants, but it is not a unit in the scientific classification of plants, and the corresponding concept of herbaceous plants is woody plants, people usually call herbaceous plants "grass", and woody plants are called "trees", but occasionally there are exceptions, such as bamboo, which belongs to herbaceous plants, but people often see it as a tree.

Algae plants. Key features:

There are unicellular and multicellular, simple structure, no differentiation of roots, stems and leaves;

The whole body absorbs water and inorganic salts from the environment, and there are chloroplasts in the cells that can carry out photosynthesis.

Typical representatives: freshwater algae: Chlamydomonas (unicellular algae), sponge (multicellular algae, green filamentous);

Marine algae: seaweed, kelp.

It can be used as bait for fish;

It can be eaten, such as kelp, seaweed;

It can be used medicinally, such as algin, agar, etc., extracted from algae.

Mode of reproduction: It can produce spores and reproduce offspring by spores, that is, spore reproduction, and the reproductive process is inseparable from water.

Bryophytes. Key features:

Generally, it has stems and leaves, there are no ducts in the stems, and there are no veins in the leaves, so there is no conduction tissue;

There are no real roots, only short, thin false roots. It is sessile, so the plants are usually short;

Leaves have only one layer of cells, containing chloroplasts, which can carry out photosynthesis and can also absorb water and inorganic salts;

The fertilization process is inseparable from water.

Typical representatives: There are about 20,000 species of bryophytes on the earth, and there are more than 2,800 kinds of bryophytes in China.

Function: Pioneers in nature, many bryophytes can secrete a liquid, which slowly dissolves into the surface of the rock, accelerates the weathering of the rock, and promotes the formation of soil, so bryophytes are also the pioneers of the bright growth of other plants;

promote the terrestrial use of marshes;

Because the leaves are composed of only one layer of cells, toxic gases are easy to invade, which can be used as an indicator plant to monitor the degree of air pollution.

Conserve soil and water. Mode of reproduction:

It is able to produce spores and reproduce offspring by spores, that is, spore reproduction, and the reproductive process is inseparable from water.

Fern. Key features:

It has real roots, stems, leaves, conduction tissues and mechanical tissues, and the plants are relatively tall;

There are many sporangia on the back of the leaf, and there are a large number of spores in the sporangia;

The process of orange fertilization is inseparable from water.

Typical representatives: there are about 12,000 species of ferns on the earth, and about 2,600 species in China, including Manjianghong (aquatic fern), kidney fern, clemat fern, and Guanzhong.

Purpose: Ancient ferns form coal;

The young leaves of the fern are delicious wild vegetables, and they are known as the "king of mountain treasures".

Manjianghong can be used as green manure and feed, and Guanzhong, curly cypress and so on can be used for medicinal purposes;

Kidney ferns, miscanthus and nest ferns are available for ornamental purposes.

Mode of reproduction: It can produce spores and reproduce offspring by spores, that is, spores to reproduce, and the reproductive process is inseparable from water.

Similarities: Algae, bryophytes and ferns share the common characteristic that they cannot produce seeds, and their reproduction is spore reproduction.

Differences: First, the living environment is different.

1. Algae plants: most of them live in water, and a few live on dark and damp land.

2. Bryophytes: dark and damp land.

3. Ferns: warm and humid land.

Second, the morphological and structural characteristics are different.

1. Algae plants: unicellular or multicellular, without differentiation of rhizomes and leaves.

2. Bryophytes: have stems and leaves, no roots, and no conductive tissues.

3. Ferns: there is differentiation of rhizomes and leaves, and there are conductive tissues.

Third, the role in the biosphere is different.

1. Algae plants: medicinal, edible, releasing oxygen.

2. Bryophytes: Pioneer plant, indicator plant for soil and water conservation, and monitoring air pollution.

3. Ferns: medicinal, edible, green manure, ornamental, ancient ferns turned into coal.
