How many plant classifications, what are the classifications of plants?

The so-called seven-level classification is the legendary - genus and species of the Boundary Gate Compendium family?

It is estimated that it is difficult to find ......

Poplar: Planta, Angiosperm phylum, Dicotyledonous Plantates, Salixaceae, Populus spp.

Metasequoia: Planta, gymnosperms, pine, fir material.

That's all I can find ......

There are seven levels of biological taxonomy: kingdom, phylum, class, order, family, genus, and species.

Poplar: Planta, Angiosperm phylum, Dicotyledons, order, Salixaceae, Populus spp., poplar.

Metasequoia: Planta, Gymnosperms, Piniaceae, order, Fir family, Metasequoia, Metasequoia.

There are seven levels: kingdom, phylum, class, order, family, genus, and species.

Angiosperm. Gymnosperm.

The morphology of the stem: it can be divided into five types: trees, shrubs, sub-shrubs, herbs, and vines, among which bamboo is a herbaceous plant. Ecological Habits:

There are five kinds of terrestrial, aquatic, epiphytic, parasitic and saprophytic, and it should be noted that crystal orchid is a saprophytic plant. Growth cycle: It is divided into three types: annual, biennial and perennial, among which cabbage and other plants are mostly annual.

How plants are classified.

1. The morphology of the stem.

Plants can be divided into five kinds according to the morphology of the stem, including trees, shrubs, sub-shrubs, herbaceous plants, and lianas, among which chrysanthemums, lilies, impatiens, bamboos and other herbaceous plants have no growth rings in cross-section, and the plants will lose their vitality once they bloom.

2. Ecological habits.

Plants can be divided into five species: terrestrial plants, aquatic plants, epiphytes, parasitic plants, and saprophytes according to ecological habits.

3. Growth cycle.

If the plant is divided according to the growth cycle, it can be divided into annual plants, biennial plants, and perennial plants, among which bamboo is a perennial plant, but has annual and biennial varieties, and cabbage, beans and other vegetables are mostly annual plants.

1. Classification according to reproductive mode, spore plants.

It is divided into algae plants, bryophytes, and ferns.

Seed plants. It is also divided into gymnosperms.

and angiosperms.

2. Divide according to low and high.

Higher plants are further divided into bryophytes, ferns, and seed plants.

The lower divisions are algae, plants and fungi.

Plant. 3. Classification according to the morphology of plant stems.

Arbor. , shrubs, subshrubs, herbaceous plants.

Liana. 4. Classification according to the ecological habits of plants.

Terrestrial plants, aquatic plants.

Epiphytes, parasitic plants, saprophytes.

5. Classification according to the life cycle of plants.

Annuals, biennials, perennials.

Gymnosperm.

Plant ClassificationPlant ClassificationGymnosperms are primitive seed plants with a long history of occurrence and development. The first gymnosperms appeared in the Paleozoic, and in the Mesozoic to the Cenozoic they were the dominant plants found on all continents.

Gymnosperms are mostly trees, a few shrubs or vines, usually evergreen, with needle-shaped, linear, scaly-shaped leaves, and rarely flattened broad-leaved (such as bamboo cypress). Most secondary xylem have only tracheids, and very few have ducts such as ephedra.

Angiosperm.

About 100 million years ago, gymnosperms flourished and declined, and angiosperms developed to become the most widely distributed and diverse plants on the earth. Angiosperms are also called flowering plants, flowering plants, and they have real flowers.

These beautiful flowers are an important organ for their reproduction offspring and are a distinguishing feature that distinguishes them from gymnosperms and other plants. There are more than 10,000 genera and about 300,000 species of angiosperms, accounting for half of the plant kingdom, and it can be said that many of the flowers and plants we see belong to angiosperms.

Bryophytes

Plant classification: bryophyta phylum green, seedless greenery. There are at least 18,000 species, which can be divided into 3 classes, mosses, mosses and hornworms. Most bryophytes are 2 5 cm tall, and a few species are up to 30 cm tall.

Bryophytes are found all over the world, from the polar regions to the tropics, and flourish most in humid environments, but they are not sea-dwelling and are highly tolerant of prolonged dry and freezing conditions. It has important economic value for human beings and can be used in agriculture, horticulture, and also as an energy source. Certain bryophytes are used as ornamental plants, such as in bryophyte gardens.

Ferns

Plant classification: Ferns are a general term for lowland wood-growing plants from the Devonian period. They need water as part of the regeneration cycle, and since then they have developed a variety of different species, and today they are still a very vigorous plant, many of which are beautiful and have high ornamental value, and are famous for their foliage plants. Such as clemat fern, nest fern, staghorn fern, alder, viburnum fern, kidney fern, etc., especially Boston fern.

Algae plants

Plant ClassificationAlgae plants include several different species of organisms that produce energy through photosynthesis. It is generally considered to be a simple plant, and some algae are related to higher plants. Although other algae appear to derive their photosynthesis ability from blue-green algae, they have separate branches in evolution.

There are about 450,000 species of plants.

Common living species are: trees, shrubs, rattans, grasses, ferns, green algae, lichens, etc. For example:

Spider plant, pothos, fortune tree, rich bamboo, junzi orchid, hydrangea, bamboo, rhododendron, tiger tail orchid, moon flower, rose, rose, petunia, magnolia, cherry blossom, peony, peony, spring flower, begonia flower, peach blossom, pear flower, seaweed, kelp, copper coin grass, anthurium and other plants.

Introduction to the Phytonucleus:

In nature, all living organisms belong to living things. Organisms should be divided into several kingdoms, and the organisms that can live sedentary and autotrophic are called the plant kingdom, referred to as plants. Plants can be classified into seed plants, algae plants, bryophytes, ferns, etc.

Most of the energy of green plants is obtained from sunlight through photosynthesis, and the temperature, humidity, light, and fresh water of the stove orange are the basic needs of plants for survival.

Angiosperms have six major organs: roots, stems, leaves, flowers, fruits, and seeds. Green plants have the ability to photosynthesize - with the help of light energy and chlorophyll, under the catalysis of enzymes, water, inorganic salts and carbon dioxide are used for photosynthesis, releasing oxygen and producing organic matter such as glucose for plant use.

Plants refer to a class of multicellular organisms in the biological kingdom that are capable of photosynthesis to obtain energy and carbon sources from sunlight and carbon dioxide. Based on their characteristics and characteristics, plants can be divided into four main groups: algae, bryophytes, ferns, and seed plants.

Algae are the simplest plants and include both unicellular and multicellular seaweeds. Locust or bryophytes are vascular plants, such as mosses and horned mosses, that do not have true roots, stems, and leaves. Fern lead woods are plants with vascular systems, such as ferns and lycopodiums, which have true roots, stems, and leaves.

Seed plants are the most advanced plants and are propagated by seeds, including gymnosperms and angiosperms. Seed plants have achieved great success in evolution and have become the dominant plant group on Earth.
