The four functions of flowers:

1. Breed offspring.

The biggest role of flowers is to reproduce offspring, and most flowers bloom every spring, when bees fly over and bring pollen from the male flowers to the female flowers for pollination, after which the flowers produce seeds. Some flowers are pollinated by self-pollination, but most flowers are pollinated by external substances.

Some plant flowers with medicinal value also have a certain medicinal value, and the plant flowers that can be used for medicine are, such as the flowers of the Buddha lotus, which can be used as medicinal materials for medicine, which has the effect of astringency and hemostasis, and can be used to detoxify alcohol and grass poisoning.

Ornamental plants and flowers include roses and peonies; The flowers of plants that can be used for medicinal purposes include moon flowers and peony flowers; Plants and flowers that purify the environment include chrysanthemums.

1. Breed offspring.

Reproduction is one of the four major functions of plant flowers, which produce seeds after pollination, and these seeds can be removed and sown to grow new plants. Some plant flowers are pollinated by self-pollination, while others are pollinated by external substances such as wind, butterflies, people, bees, etc.

Fourth, medicinal value.

Some flowers have medicinal value, such as the flowers of spring flowers, which have the effect of fever and headache.

1. The petals are attractive to insects. 2. The stamens are pollen-making. 3. The pistils are pollen-receptive. 4. Sepals are used to protect unopened flowers.

There are flower seeds for breeding offspring, attracting insects to have pollen, brewing tea to drink to cure diseases, and planting in the park can be watched. Like, thank you.

Breeding offspring to attract insects to spread pollen can be made into medicines, such as rhodiola. It can also be viewed.

When the flowers and plants bloom, the color of the flowers is generally brighter, and some varieties also have fragrance, which can attract insects for pollination, and the insects will impart the pollen on the male flowers to the female flowers, and after the pollination is successful and the flowers wither, there will be fruits, and the seeds will begin to multiply after the fruits are ripe.

In general, flowers have many functions, not only worthy of appreciation, but also have a fragrance that makes people feel happy.

The flower is made up of receptacles, petals, calyxes, stamens, and pistils. Among them, stamens are divided into filaments and anthers. The pistil is further divided into ovary, columella, and stigma.

Some flowers are unisexual, with only stamens or pistils, and can only be cross-pollinated by insects. The outermost leaf-like structure of the flower is called the calyx. The calyx is usually green, can be large or small, and is wrapped around the flower bud to protect the flower bud.

The calyx is composed of several sepals, and the sepals are separated and combined.

Flowers are the reproductive organs of angiosperms (angiosperms, also known as flowering plants or flowering plants), and their biological function is to combine male sperm cells with female egg cells to produce seeds. This process begins with pollination and then fertilization, which leads to the formation of seeds and their dispersal. For higher plants, seeds are their offspring and are the main means of natural distribution of species.

The combination of flowers that grow on the same plant is called an inflorescence.

Composition of flowers.

In the part, the stamens are divided into pistils and stamens. Self.

Take peony as an example

The pistil is located in the center of the flower, shaped like a small pomegranate, and the longer it grows, the more cracked it becomes, and when it opens, it has formed a large petal shape. The stamens are located around the pistils, and when they first bloom, the stamens are plump, neatly arranged, and medium-yellow. When in full bloom, the stamen is exposed, more flexible than the first bloom, and the color is light yellow.

When it is grateful, the stamen gradually dries and curls, and the stamen is milky yellow. The stamens are composed of stamens and stamens (whiskers). The stamen silk is connected to the flower center under the stamen, and the stamens are shaped like rice grains.

The green tepal that is located on the outside of the corolla is the calyx, which protects the flower buds when the flowers are not yet open.

Calyx is a general term for all sepals in a flower, which is coated in the outermost layer of the flower. The sepals are mostly green and relatively thick phyllodes, containing slightly branched vascular tissue and abundant green parenchyma cells, but there is little differentiation between palisade tissue and spongy tissue. In some plants, calyxes may specialize into large, brightly colored petal-like calyxes (similar to petals), such as aconitum and pulsatilla.

In addition to the calyx, the flowers of vermilion, strawberry, cotton, etc., have a round of green petals on the outside, called accessory

calyx), which is equivalent to the bracts of flowers.
