It turns out that there is an enlarged organ called "leaf pillow" at the base of the petiole of mimosa, and there are many parenchyma cells in the leaf pillow, which is very sensitive to external stimuli. Once it touches the leaves, the stimulation will be immediately transmitted to the occipital bone. At this time, the cytosol in parenchyma cells began to flow into the intercellular space, which reduced the expansion ability of cells, reduced the intercellular pressure in the lower occipital region, and the leaves closed and the petiole drooped. 1-2 minutes later, the cell fluid gradually flows back to the leaf pillow, so the leaves return to their original appearance.

The above phenomenon of Mimosa leaves is a physiological phenomenon, and it is also the result of Mimosa adapting to the external environment for a long time in the process of system development. Because the mimosa originated in the tropical region, where there are many storms, when the storm blows the leaflets, it immediately closes the leaves to protect them from the storm, thus gradually forming this physiological phenomenon.

Mimosa ;

It is a perennial herb or subshrub of Leguminosae. Because its leaves respond to heat and light, they will close immediately when touched by external force, so it is named mimosa. Shaped like a fluff ball. After flowering, it bears pods and the fruit is oblate. The leaves are feather-like compound leaves, alternating with each other and arranged in a palm shape. Flowering after midsummer, with oblong flower heads and 2-3 flowers in leaf axils. The flowers are white and pink, with bell-shaped calyx, 8 tiny calyx teeth, 4 petals and 4 stamens, and the ovary is hairless. The pods are flat, each pod node 1 grain, and fall off at maturity. Flowers bloom in September. ?

The flowers, leaves and pods of mimosa have a good ornamental effect and are easy to survive, so it is suitable for potted plants on balconies and indoors (people who eat mimosa or contact it too much can also cause hair loss). It can also be planted in yards and other places. Mimosa is different from ordinary plants. When it is touched, the petiole droops and the small leaves close, so people understand it as "shy grass", so it is called grass-sensitive, grass-drinking, grass-shy, grass-ashamed and grass-ugly (Cantonese). Native to tropical South America, it likes to be warm and humid, and has general requirements for soil.
