Taxonomic index of plants, introduction to plant taxonomy

Aquatic plants refer to plants suitable for growing in water, such as bowl lilies and daffodils; Terrestrial plants, which are more common in life, such as dahlias, cosmos, stones, irises, etc.; Epiphytes, plants that grow on trees or branches, such as pineapple, East Asian whiplis, Mirran, etc.; aerial plants with well-developed root systems, such as spider plants, banyan trees, ivy, etc.; Parasitic plants, such as cistanche, dodder seeds, etc.

Aquatic plants refer to plants that grow in water, collectively known as aquatic plants, usually this plant has a developed root system, but also has a special aeration tissue, which can ensure the normal growth of the root system in the water, such as common bowl lotus, daffodils, tulips, etc.

Terrestrial plants are more common in life, ubiquitous, and are also one of the greening plants in nature, this plant has a wide coverage ability, strong adaptability, and has the characteristics of drought tolerance and cold resistance, such as common dahlias, cosmos, rocks, irises, cornflowers, cockscombs, etc.

Epiphytes are plants that do not grow on the ground, but on trees or branches, mainly to absorb nutrients in the branches to grow and develop, such as the common pineapple, East Asian whip moss, Mirran, small-leaved flaglia, spiny fruit moss, tree flat moss, tiger head orchid, dendrobium nobile, etc.

Aerial plants have strong adaptability, developed root system, the required nutrients and water mainly come from the air, this plant has no adventitious roots, common spider plant, banyan tree, ivy, pothos, pineapple pineapple, pineapple iron orchid, etc.

Parasitic plants mainly rely on green plants to absorb nutrients and water, have strong reproductive ability, and are rich and diverse in shape, but they are harmful to the host, such as the common cistanche, dodder seed, wild mushroom, liedang, mulberry parasitism, etc.

Plant taxonomy and plant systematics: It is the science of classifying plants according to their characteristics, the relationship between plants, and the order of evolution, and establishing and gradually improving the evolutionary system of plant groups at all levels on the basis of research. The two are often used interchangeably, but plant systematics places more emphasis on the phylogenetic relationships between plants, i.e., genealogies.

Since the 50s, with the development of other disciplines, further sub-disciplines such as plant chemical taxonomy, plant cell taxonomy, plant ultrastructure taxonomy and plant numerical taxonomy have been produced. In particular, the development of molecular systematics in the late 80s has provided a new means for the phylogenetic study of plants. In addition, the study of the classification of a specific group of plants has also given rise to corresponding sub-disciplines, such as: bacteriology, mycology, algal botany, bryobotany.
