1. Why does Dancing Grass Dance
Dancing Grass is a particularly interesting vertical shrub whose ancestral home is in India. Mainly distributed in the deep forests around Yunnan, Guizhou and Sichuan in China, it has been listed as rare and endangered plants by the state and protected. However, apart from its rarity, its dance performance is more interesting. People have always wondered why dancing grass can dance.
In fact, scientists are arguing about why dancing grass can dance! Scientists don't have a unified understanding, and their explanations are different. Some scientists believe that the dance of dancing grass is related to sunlight. If there is light, it will dance, but if there is no light, it will rest, just like a sunflower turning to the sun.
However, some people think that dancing behavior is caused by the change of the intensity and direction of weak current in plants or the change of the growth speed of plant cells.
Some scientists believe that the wonderful habit of dancing grass is a kind of biological adaptability. When it dances, the dancing leaves have a threatening effect and can avoid some insects. In fact, this is also a self-protection function of plants, and it is also the most accurate statement.
second, a special skill to exercise for survival
Dancing grass is a perennial deciduous shrub of Papilionidae and Phaseolus. About fifty or sixty centimeters tall, and the stem is as thick as a thumb. Flowers and fruits in autumn and leaves in winter. The flowers are lipped and pink. The seeds are dark brown, and the shell is hard, and the shell is wrapped with a layer of shiny wax. This wax has a sweet smell. There is a big leaf at the top of each petiole on its branch, and two leaflets grow symmetrically behind the big leaf. These leaves are particularly sensitive to sunlight.
once exposed to sunlight, the two leaflets at the back will always dance around the petiole against the sunlight. From sunrise to sunset, it will hang down its branches wearily and start to rest until the sun comes out the next day, and it will start dancing again.
The dance of grass is closely related to the temperature. When the sun rises and the temperature reaches 1, when there is no wind, the two leaflets will automatically dance around the big leaves with the petiole as the axis. After a rotation, they will rebound quickly, and then rotate and rebound day and night.
sometimes it swings up and down, sometimes fast and sometimes slow, which is quite rhythmic. However, petioles and big leaves did not move. It was observed that the rotation speed of lobules increased with the increase of temperature. When the temperature rises to 3℃, the lobular rotation is the most active. Even on cloudy days, its leaflets will swing and rotate like dragonflies or butterflies dancing among flowers, which is full of fun. Some people say it flutters like a chicken feather. Therefore, it is called feather grass. Some people think it's like a pair of mandarin ducks. It's like a phoenix that wants to burn. It's called wind and grass.
People say that it dances charmingly, and it is also called charming grass. Some people also see its two leaves dancing around the big leaves forever, which is infinitely loyal, just like a loyal minister defending the monarch, so it is also called two generals protecting the emperor. Anemone's hometown is in tropical areas, such as India and Sri Lanka mentioned above. On the question of why dancing grass dances, in fact, tropical plants are afraid that the water inside the plants will evaporate too quickly out of survival instinct, so when the sun shines on it, it keeps dancing two leaflets to resist the scorching sun. It's like people waving fans to drive away the heat wave in hot summer. This is its special skill to adapt to the environment and strive for survival.
