Flowers are mainly used for beautifying the environment and interpersonal communication, and can also be used as food sources. Flowers consist of corolla, calyx, receptacle and stamens. They have all kinds of colors, some of which are gorgeous and fragrant. The reproductive organs of angiosperms (angiosperms, also known as flowering plants) have the biological function of combining male sperm cells with female egg cells to produce seeds.
This process begins with pollination, then fertilization, after which seeds are formed and spread. For higher plants, seeds are their next generation, which grow into flowers, pollinate and fertilize, thus prolonging the life of this variety of flowers. It is also the main means of species distribution in nature. The combination of flowers planted on the same plant is called inflorescence.
Morphogenesis
The reproductive organs of angiosperms. Typical flowers have limited growth on the short axis, including calyx, corolla, stamens and pistils that produce germ cells. Some scholars think that the spore bulbs of gymnosperms are also "flowers", while most people think that only angiosperms have flowers, so angiosperms are also called flowering plants.
The various parts of flowers are not easily influenced by the external environment and change little, so people have long regarded the morphological structure of flowers as the main basis for the classification, identification and systematic evolution of angiosperms (see angiosperms).
