Which plants can move?

sunflower

The sunflower gets its name because the top of the young plant in the early stage of its growth and the young flower disk in the middle stage will rotate with the rotation of the sun. The movement of sunflowers is a typical phototropic movement. When the sun rises, the east side of the emerald green sunflower is exposed to sunlight, causing the vigorously growing young stems at the top to have more auxin distributed on the west side that is not exposed to the sun. The cells on this side grow vertically faster, resulting in the young stem bending toward the slower-growing east side, that is, the top of the sunflower (disc) bends to the east in the morning. As the sun moves in the sky and changes the direction of light, the top of the sunflower (disk) also changes direction constantly, standing upright at noon and bending to the west in the afternoon. The sunflower also moves with the sun rising in the east and setting in the west.

Mimosa

Plants are different from animals. They do not have a nervous system or muscles, and cannot perceive external stimuli. However, mimosa is different from ordinary plants. When it is touched by the outside world, its leaves will droop and the leaflets will close. This action is understood by people as "shy", so it is called mimosa. This special ability of mimosa has certain historical roots. Its homeland is Brazil in tropical South America, where strong winds and heavy rains are common. Whenever the first drop of rain hits the leaves, it immediately closes its leaves and its petioles droop to avoid damage from the storm. This is an adaptation to changes in external environmental conditions. In addition, the movement of the mimosa can also be seen as a form of self-defense. If an animal touches it, it will close its leaves, and the animal will not dare to eat it anymore.

Water Lily

Water lily, also known as meridian lotus and water celery flower, is a perennial aquatic plant belonging to the genus Nymphaea of ​​the Nymphaeaceae family. Water lily is a precious aquatic flower. As the sun sets, the flowers of the water lilies will gradually close, as if the flowers are going to sleep at night, which is how the water lilies got their name. Because the water lily opens during the day and closes at night, it is also known as the "Sleeping Beauty among flowers". A poet once described water lilies like this: "Don't get me wrong, we don't like to sleep, we just don't like the twilight, so we close our flowers at night. After midnight, we open up early again, welcoming the rising sun and the arrival of fresh air in advance."

Dancing Grass

Dancing grass, also known as dancing grass, lover grass, windless grass, amorous grass, romantic grass, courtship grass, etc., is a perennial woody plant belonging to the genus Dancing grass of the Fabaceae family. Each branch petiole has three elegant leaves. When the temperature reaches above 25℃ and under the stimulation of 70 decibels of sound, the two leaflets will "dance on their own" around the middle leaf, hence the name "dancing grass", giving people a sense of freshness and mystery. Dancing grass is produced in some provinces and regions in southern China. Dancing grass is grown in many botanical gardens today and is attracting much attention as a moving pet.
