Classified by the form of plants: woody plants (arbors, shrubs, sub-shrubs), herbs, vines;

Classified according to the ecological habits of plants: terrestrial plants, aquatic plants, epiphytes, saprophytes;

Classified by plant life cycle: one or two annual plants, perennial plants;

According to the types of plant rhizomes: bulbous plants, perennial plants, etc.;

What are their characteristics:
Woody plants: The roots and stems are thickened and grown to form a large amount of xylem, and the cell walls are mostly lignified solid plants;
Herbs: The stems are "grass stems". The stems are densely packed with relatively small vascular bundles. Between the vascular bundles are a large number of parenchyma cells. The outermost layer of the stem is a tough mechanical tissue. The vascular bundles of herbaceous plants are also different from woody plants. The woody part of the vascular bundles is distributed on the outside and the phloem is distributed on the inside. This is completely opposite to woody plants. In addition, the vascular bundles of herbal plants do not have cambium and cannot be continuous Grow, so the tree will thicken year by year but the grass has no such ability;

Liana: The plant body is slender and cannot stand upright. It can only attach to other plants or supports, entangle or climb up-growing plants, mainly climbing;
Terrestrial plants: the general term for plants that grow on land, which mainly grow on land;

Aquatic plants: The leaves are usually thin, some of the leaves are cracked like silk or thread-like; some are ribbon-shaped; some are broad and transparent, the roots are generally underdeveloped, and the leaf surface is not thickened or waxy. Or suppository;

Epiphytes: It only attaches to other plants and only uses the natural stored water in the epiphytic parts without absorbing nutrients. It should not damage the attached plants and have strong adaptability. On the one hand, the requirements for water and fertilizer are not high, on the other hand Once the environment is suitable, grow and reproduce quickly;
Saprophytic plants: mainly bacteria and fungi. They use dead or decomposing organisms or dead parts of plants growing nearby as a source of nutrients. Crystal orchid is one of the few saprophytic plants that bloom;

Annual plant: A non-woody plant that completes its life cycle (germination, growth, flowering, fruiting, and death) within one year. During the rapid growth period of several weeks or months, it stores a large amount of nutrients to maintain its flowering and fruiting growth period;
Biannual plant: Any non-woody plant that completes its life cycle (germination, growth, flowering, fruiting, and death) within two growing seasons. In the first growing season, biennial plants grow roots, stems, and leaves; in the second growing season, they bloom, bear fruit and set seeds, and then die;

Perennial plants: plants that can live for more than two years, the above-ground parts die every year, and new branches will grow from the underground parts in the spring of the second year, and they will bloom and bear fruit;

Perennial plants: It has an underground part that has survived for many years. It is planted for many years at a time. The cold-resistant and semi-cold-resistant perennial flowers of temperate zone are dormant, and they are commonly reproduced by ramets;
Bulbous plants: underground organs (including roots and underground stems) swelled into masses, roots, and globules. All have underground storage organs, which can survive for many years.
