plant
Plants are a major category in the biological world. Generally there is chlorophyll, but no nerves or feelings. The origin of plants can be traced back to 2.5 billion years ago.
Plants are divided into algae, ferns, bryophytes and seed plants. Seed plants are further divided into gymnosperms and angiosperms. There are more than 300,000 species.
It is the blooming and falling of angiosperm flowers that make the Cenozoic Earth with its distinct four seasons particularly beautiful.

interesting plants
Meat-eating plant - Nepenthes
Nepenthes is the collective name for plants of the genus Nepenthes. It is the only genus of the Nepenthes family and a variety of perennial herbaceous plants that can prey on insects. Its main origin is tropical Asia. It is a ground plant and a climbing subshrub. Nepenthes has a unique organ for absorbing nutrients - the pitcher. The pitcher is cylindrical with a slightly enlarged lower part. Because it is shaped like a pig pitcher, it is called Nepenthes. In Hainan, the place of origin in China, it is also called the Thunder God Pot, which means that it resembles a wine pot. Plants that obtain nutrients by capturing and digesting small animals such as insects are called carnivorous plants.
The leaves of Sunflower are generally about 0.3 meters long, and the flowers are scattered on the leaves. Sunflowers emit an alluring orchid-like fragrance that can be smelled from a distance. Sunflower grows in the dense primeval forests and vast swamps of the Amazon River Basin in South America. It is a feared man-eating plant.
Unlike ordinary plants, this flower is very responsive and powerful. If someone wants to pick its flowers, no matter if they touch its stems, leaves or petals, the slender leaves will immediately stretch out like an eagle's claws and grab the person tightly. At the same time, the large spider hiding next to the sun flower, the black widow spider, quickly came to bite the human body. The venom glands in the upper jaw of this spider can secrete a neurotoxic protein liquid. When the venom enters the human body, it will cause death.
