Htee Ka Yone Pin (Mimosa sensitive plant)

++++++++++++++++++++++++++++++++++++++++++++++++++

Hello,everyone.

This posting is about 'the Mimosa plants' which I found from "The Child who Raised Poisenous Snakes" by Can Xue from China. I had seen that plant and even played with it a few times since it grows naturally in my country. It is called " Htee Ka Yone Pin" in my language. This plant's leaflets curl up when being touched.It is interesting to look at how the plant reacts to the touch. Below are the technical definitions. I beg you to try the source link 1 coz it got a video of the plant moving.Enjoy..=)
"The scientific name is Mimosa pudica though there are other varients"

"The leaves of Mimosa have the capability to display thigmonasty (touch-induced movement). In the sensitive plant, the leaves respond to being touched, shaken, heated or rapidly cooled."


" In Mimosa, the mechanical or heat stimulus induces an electrical signal, similar to the electrical potentials in nerve cells, that can move from cell to cell at a high rate. When the electrical potential reaches specialized "motor cells" in pulvini at the base of each leaflet, the folding is caused by a rapid efflux of potassium followed by rapid water transport out of the motor cells. "
