What do you know about moving plants? Come and meet me.

There are always wonders in the magical nature, giving birth to some plants that can move. Because of their own characteristics, these plants can move spontaneously under the conditions of light and temperature. Let's take a look at the strange plants.

1. Sunflower

Sunflowers can move, which should not be uncommon, many friends also know that sunflower movement is a typical phototropic movement. Because the stem under the sunflower disk contains a wonderful plant auxin, which has the characteristic of backlight growth, it will run to the backlit side when it is exposed to direct sunlight, thus causing the backlit side to grow faster than the sunny side. therefore, as the sun moves and the direction of light changes, the sunflower disk will bend toward the sun.

2. Mimosa

When the mimosa is touched by the outside world, the leaves will droop and the leaflets close, so it is called the mimosa. The special ability of mimosa has its historical roots. It is native to Brazil, where there are often strong winds and heavy rain. When raindrops hit the leaves, the leaves close immediately and the petioles droop to avoid the damage caused by high winds and torrential rains, which is an adaptation to changes in external environmental conditions.

3. Water lilies

Water lilies are one of the most valuable aquatic flowers. As the sun sets, its flowers will gradually close, as if they have to sleep at night, hence the name. Because of the day and night curls of water lilies, it is also known as the "sleeping beauty in flowers".

4. Dance grass

Also known as dance grass, lover grass. There are three beautiful leaves on the petioles of each branch. When the temperature is above 25 ℃ and stimulated by the sound of 70 decibels, the two leaflets continue to swing up and down around the middle leaves, hence the name "dance grass", giving people a sense of freshness and mystery.

5. Flytrap

The predation organ of the flytrap is the leaf, on which there are sensory hairs. Any sensory hair is touched twice, or two sensory hairs are touched respectively. The leaves close quickly, and when the leaves clamp the insects, the bristles bite tightly together to prevent the insects from escaping.

6. Castanopsis carlesii

The leaves of Castanopsis thunbergii have glandular hairs as glittering and translucent as dewdrops, which is their insect trap. The glandular hairs are covered with glands, which can secrete a mixture of honey and mucus and digestive enzymes that attract insects. when the insects are stuck, the surrounding glandular hairs bend together, and the leaves roll up, trapping the insects firmly, and when the insects are digested and absorbed completely, the leaves and glandular hairs expand again.

7. Crape myrtle

Also known as the tickle tree, after growing up, the trunk bark falls, smooth and skinless. If people gently touch it, they will immediately shake the leaves, tremble all over, and even make a faint "cackle" sound, which is a "ticklish" systemic response.
