There are 500,000 species of plants in the world, and about 350,000 species have been named; Among them, plants with flowers account for the majority, about 200,000-250,000 species. This number is the number of types of flowers.

There are about 370,000 species of plants in the world;
It is divided into nine gates, namely:
1.There are 226,000 species of angiosperms (divided into two outlines).
172,000 species of dicots.
54,000 species of monocots.
2.There are 800 species of gymnosperms.
3.12,000 species of ferns.
4.26,000 species of moss.
5.33,000 species of algae.
6.50,000 species of fungi.
7.20,000 species of lichens.
8.There are 1,600 species of bacteria.
9.There are 2,000 species of cyanobacteria plants.
1.Angiosperm.
One of the highest phylums in the plant kingdom, together with gymnosperms, is called seed plants. Unlike other plants in that they have the characteristic of having seeds, angiosperms are one of the most advanced, most abundant and widely distributed taxa in the plant kingdom. Angiosperms have true flowers; The ovule is encapsulated in the ovary; The sporophyte is highly developed, the gametophyte is further simplified, and the endosperm is formed after fertilization. The pollen grains stay on the stigma and cannot be in direct contact with the ovules; The ovary continues to develop after fertilization to form fruits, so the seeds are coated, so they are called angiosperms.
Angiosperms began to appear in large numbers in the late Mesozoic era, and are now distributed all over the world, with as many as 300,000 species. They have great economic value. It can be divided into dicots and monocots (magnolia).
Magnolia (Dicotyledons): The embryo of the seed has two cotyledons; The vascular bundles of the stem are arranged in a circular shape with a cambium layer, which can make the stem continue to thicken. The veins are reticulated, and the parts of the flower are 5 in number, sometimes 4 in number. Plants have a variety of habits (slender herbaceous to stout trees).
This class contains the vast majority of common plant groups, and monocots are taxonomically thought to have evolved from dicots.
Lilia (Monocots): Embryo with 1 cotyledon. The vascular bundles of stems are mostly scattered in a stellar arrangement, usually without a cambium layer and cannot be gradually thickened. Leaf veins are usually parallel or arcuate, sparsely reticulated or pinnated; The parts of the flower are usually 3 in number; The taproot is generally underdeveloped and is replaced by fibrous roots.
It is now agreed that monocots are late in evolution; Whether or not they belong to a natural group is still debated. Although these plants are far less numerous than dicots, they are of comparable importance.
Remarks: Taxonomic methods Phyla, phylum, class, order, family, genus, species, the kingdom is divided into animal kingdom and plant kingdom; The plant kingdom is divided into nine gates; The phylum Angiosperms is further divided into two outlines, Dicotyledons & Monocots. :)
