When touching Mimosa, we can find that the leaves of Mimosa will be closed. This is because there is a part at the petiole and the base of the leaves, called the leaf pillow, which is the main reason for the shyness of Mimosa. When the leaves of Mimosa are stimulated, the cell fluid of the cells inside the leaf pillow will be discharged, causing the imbalance between the upper part and the lower part, leading to the closure of the leaves.
This phenomenon of Mimosa occurs very quickly. It takes a short time before and after, but to recover, it takes 5 minutes - 10 minutes
Shy Mimosa may also have something to do with the environment. Mimosa herb is produced in the tropics, where it is mostly rainy weather, often encounter storm. Therefore, Mimosa in order to protect themselves, when encountering rain, they will close their leaves in time, which can be said to be biological adaptability.
In winter, Mimosa this shy phenomenon, is relatively small. This is mainly because of the influence of temperature
In winter, the temperature is very low. Under the influence of low temperature, the permeability of the cytoplasm of Mimosa leaves will be weakened, which will lead to its slow response to external stimuli, so when stimulated, Mimosa leaves will not close so fast, and it will no longer be shy
With the gradual decrease of winter temperature, Mimosa will completely lose this characteristic. Especially in the new leaves, the performance is more obvious
