Why does the mimosa move?

Mimosa can move because its leaves have a "swelling effect".

At the base of the petiole of mimosa, there is a thin-walled cell tissue, which is full of water leaf pillows. When the mimosa is touched and the leaves vibrate, the water in the cells at the lower part of the occipital immediately flows to the upper and both sides. As a result, the lower part of the pillow was flat like a deflated bicycle tire, the upper part was bulging like a deflated ball, and the petiole drooped and closed.

When the leaves of mimosa are stimulated to close, it will produce a kind of bioelectricity, which will transmit the stimulated information to other leaves, and the other leaves will close in turn. When the stimulation disappears, the leaves are gradually filled with water under the pillow, and the leaves are reopened and restored to their original state.

Not only mimosa, but also spiders act by expanding and squeezing. A spider's leg is not a muscle, but a liquid. By flexibly adjusting the pressure of the liquid, the legs can advance and retreat freely.

Characteristics of mimosa

1, strange shape: Mimosa leaves are opposite, shaped like feathers, and look a bit like miniature banana leaves. Its flowers are spherical, white and pink.

2, can predict the weather: when touching the mimosa leaves, slowly shrink, open immediately after closing, indicating that the weather will be rainy; If it closes quickly, but opens slowly, it means it will be sunny.

3, can predict earthquakes: Mimosa leaves are generally open during the day and closed at night, but if Mimosa leaves are closed during the day, an earthquake is likely to occur. In addition, if the mimosa suddenly withers, it also indicates an earthquake.
