What are the angiosperms in the world?

1. Moon flowers, known as the queen of flowers, also known as "moon moon red", is an evergreen, semi-evergreen low shrub that blooms in all seasons, generally red, or pink, occasionally white and yellow, and can be used as an ornamental plant.

2. Roses, is the common name of the order Rosaceae, the Rosaceae family, the genus Rosa and a variety of cultivated flowers. The branches are soft and droopy and densely prickly, and they bloom only once a year. <>

3. RoseIt is a common name for some plants of the genus Rosaceae, mainly referring to varieties and horticultural varieties of Rosa vine. Most of them are small flowers that climb the fence in the form of vines, and they are deciduous shrubs native to China with strong variability.

4. Cherry blossomsCherry blossom is not a single flower, but a collective term for many species and varieties. In horticulture, cherry blossom is the collective name for all species of the subgenus Plum in the family Rosaceae.

5. OsmanthusIt is the customary name of many trees of the genus Rhinoceros, the representative species of Rhinoceros, also known as rock cinnamon, is an evergreen shrub or small tree of the family Rhinocerosaceae, with firm skin and thin bark, oblong leaves with pointed faces, opposite, and does not wither in winter.

Angiosperms include cherry blossoms, osmanthus, peonies, beans, cereals, potatoes, poplars, melons and fruits, mulberry trees, maple poplars, hawthorns, plane trees, poplars, roses, poplars, willows, weeping willows, begonias, birches, elms, elms, figs, magnolias, magnolias, smiles, tulipwood, Qiaoji Nantianzhu, camellia, heather, bauhinia, apples, purple bamboos, persimmons, cherries, etc.

Angiosperms are the most evolutionary, diverse, widely distributed and adaptable group in the world today. It is known that there are more than 200,000 species of angiosperms in the world, accounting for more than half of the total number of plants. There are more than 2,700 genera and more than 30,000 species of angiosperms known in China.

Angiosperm plants have a very close relationship with human beings, such as more than 2,000 kinds of angiosperms that can provide food in my Chenkuan and country; There are more than 300 species of fruit trees; There are countless flowers and plants; There are 10,027 species of medicinal angiosperms (including taxonomic units below species), accounting for 90% of the total number of medicinal plants in China, and it is the group with the largest number of medicinal species, and most of the traditional Chinese medicine comes from angiosperms.

The best available evidence of fossilized pollen grains and leaves suggests that angiosperms originated in the Early Cretaceous about 100 million years ago. In the older Cretaceous sediments, the angiosperm fossil record pales in number with fossils of ferns and gymnosperms. It wasn't until the end of the Cretaceous period, 80 million 90 million years ago, that angiosperms dominated much of the planet.

1. Rhododendron: also known as mountain red and mountain pomegranate, it is an evergreen or ordinary green shrub. According to legend, there were cuckoo birds in ancient times, crying day and night and coughing up blood, dyeing red flowers all over the mountain, hence the name.

Rhododendron generally blooms in spring, with 2-6 flowers per cluster, and the flowers are thick and canopy-shaped, with red, light red, apricot red, snow blue, white, etc., and the flower color is lush and gorgeous.

2. Chrysanthemum: Chrysanthemum is also an angiosperm plant, chrysanthemum is one of the top ten famous flowers in China, one of the four gentlemen in the flower, and one of the four cut flowers in the world, with the highest output. Because the chrysanthemum has the character of cold and proud snow, there is Tao Yuanming's famous sentence of "picking chrysanthemums under the east fence, and seeing Nanshan leisurely".

In ancient myths and legends, chrysanthemums were also endowed with the meaning of auspiciousness and longevity.

3. Populus euphratica: Populus euphratica can be up to 200 years old, with a straight trunk, 10-15 meters high, and sparse shrub-like. The leaves are peculiar, because they grow in extremely arid desert areas, in order to adapt to the arid environment, the leaves that grow on the young branches of young trees are as narrow as willows, but the leaves on the old branches of large trees are round like poplars.

Common angiosperms include weeping willow, white birch, elm macro, state tree, mulberry, magnolia, peony, apple, peach, plum, apricot, yueji, rose, cherry, cherry blossom, etc.

Angiosperms are characterized by having six organs: roots, stems, leaves, flowers, fruits, and seeds. Most of the food and nutrients for humans are angiosperms. Angiosperms also provide countless raw materials for construction, papermaking, textiles and plastic products, oilseeds, fibers, sugar, spices and medicines, masking beverages, and so on.

Ecologically, angiosperms are important to humans by creating windbreaks and planting cover plants to prevent soil erosion and seawater erosion of land. Angiosperms play an important role in the development of human cultural consciousness and provide a large number of symbols for the cultures of peoples all over the world.

Plant characteristics

Angiosperms are the most advanced type of the plant kingdom, the most perfect and old plants on the earth, and they have been overwhelmingly dominant on the earth since the Cenozoic Era. There are more than 10,000 genera and more than 300,000 species of angiosperms, accounting for half of the plant kingdom, and there are more than 2,700 genera and about 30,000 species in China.

Angiosperms can have so many species and have an extremely wide range of adaptability, which is inseparable from the complexity and perfection of its structure, especially the characteristics of the structure of the reproductive organs and the reproductive process, which provide the internal conditions for it to adapt to and resist various environments, so that it constantly produces new mutations and new species in the process of the contradictory struggle of survival competition and natural selection.

Generally, there are many angiosperms, such as rhododendrons, magnolias, miscanthus, snakeroots, maples, Yunnan maple, apples, apricots, chrysanthemums, maple trees, catalpa maples, orchids and peach trees, etc., angiosperms are characterized by real flowers, calyxes, receptacles and pistils, and also have double fertilization, and the sporophyte is more developed, and the gametophyte will degenerate, in addition to producing seeds, seeds will also have endosperm.

Angiosperms are characterized by having true flowers, limb calyxes, receptacles and pistils, also having double fertilization, and the sporophyte is relatively developed, while the gametophyte will be degenerated, and will also produce seeds, which will also have endosperm.

Angiosperms are mainly divided into monocots and dicots, and there are many angiosperms, such as rhododendrons, magnolias, miscanthus, snake root wood, maple sorghum, Yunnan maple, apple, apricot tree, chrysanthemum, maple family, catalpa maple, orchid and peach tree, etc.

Snake root wood. Snakeroot wood is an angiosperm and belongs to the dicot plants of angiosperms, snakeroot wood is a shrub with downy on the inside of the calyx, sparse skin pores on the stem, and likes to grow in soft and moist places.

Acer japonica. Acer is an angiosperm and belongs to the dicots of angiosperms, the trunk of the maple is very straight, the leaves are papery, and it will be divided into 3 or 5 lobes, which belongs to the neutral and sunny tree species.

Aceraceae. Acer family is angiosperm history blind, belongs to the angiosperm of the dicot plant, maple family leaves are very special, belonging to single-leaf pinnate or palmate compound leaves, the color is red, with a certain cold resistance.

Azalea. Rhododendron is an angiosperm and belongs to the dicotyledons of angiosperms, the leaves of azaleas are ovate and the flowers are more showy, and the rhododendrons are plants that like shade and also like to grow in places with high air humidity.

Common angiosperms are peach trees, orchids, chrysanthemums, etc.

The peach tree is a deciduous tree of the Rosaceae family, with a flat canopy, which blooms every spring and has a strong fragrance. Orchids are perennial herbaceous plants, and when they enter the flowering period, the flowers open and are bright and beautiful in color. Chrysanthemums bloom in autumn every year, and when they bloom, they are bright in color and have high ornamental value.

It is known that there are more than 200,000 species of angiosperms in the world, and most of the food and nutrition of human beings are higher than angiosperms, such as cereals, beans, potatoes, fruits and vegetables, etc., and also indirectly provide livestock for pastures.

Angiosperms also provide countless raw materials for construction, papermaking, textiles and plastic products, oilseeds, fibers, sugar, spices, wax, medicines, resins, tannic acids, anesthetics, beverages, etc. Ecologically, angiosperms are important to humans by creating windbreaks and planting cover plants to prevent soil erosion and seawater erosion of land.

Angiosperms

Angiosperms also provide most of the materials needed for recreation and recreation such as building gardens, parks, sports fields, street greening, residential decoration, etc. Angiosperms are the most evolutionary, diverse, widely distributed and adaptable group in the plant kingdom in the world today. It is known that there are about 300,000 species of angiosperms in the world, accounting for more than half of the total number of plants.

There are more than 2,700 genera and more than 30,000 species of angiosperms known in China. Yanqing acorn angiosperms have a very close relationship with human beings, such as more than 2,000 kinds of angiosperms in China that can provide food, and more than 300 kinds of fruit trees. There are 10,027 species of medicinal angiosperms, accounting for 90% of the total number of medicinal plants in China.

It is the group with the largest variety of medicinal species, and the vast majority of traditional Chinese medicine comes from angiosperms.

What are angiospermsAngiosperms, also known as green flowering plants, are often referred to as angiosperms in taxonomy. It is the highest class of the plant kingdom. Since the Cenozoic, they have dominated the planet.

There are more than 10,000 genera of angiosperms, accounting for almost half of the plant kingdom, and many of the plants we come into contact with belong to angiosperms.

What are the angiospermsThe unique feature of angiosperms is that they have real flowers, so they are also called flowering plants. Flowers are an important organ for them to reproduce their offspring. Common angiosperms include weeping willow, birch, elm, mulberry, magnolia, peony, apple, peach, plum, apricot, yueji, rose, cherry, cherry, cherry, etc.
