The secret of mimosa, pictures of mimosa

Mimosa, also known as sensitive grass and shy grass, is a perennial herb of the legume family. It is native to tropical regions of America and is generally found in bushes. There are usually more than a dozen pairs of symmetrically distributed leaves on its leaf stems. It looks like a feather and is emerald green in color. It also blooms, but the flowers are smaller, white and pink in color, and have a better ornamental effect.

1. The Secret of Mimosa

There is an organ called "pulvinus" at the bottom of the petiole of mimosa, which contains relatively abundant parenchyma cells. These cells are very sensitive. Once stimulated by the outside world, the cell fluid in the cells will flow to other places, thereby reducing the expansion of the cells. This reduces the pressure on the cells of the pulvinus, making the leaves appear closed. This is what the outside world sees as the leaves of the mimosa automatically closing when touched.

Because of this "secret" of mimosa, its leaves can well predict weather and earthquakes. Because the leaves of mimosa are generally open on sunny days and during the day, and closed at night and on rainy days. If its leaves close slowly but open quickly after being stimulated, it means that it may turn cloudy or rainy. If it closes quickly and then opens slowly, it means the weather is about to clear up. If it suddenly opens its leaves at night or closes its leaves during the day, it means that an earthquake may be coming soon.
