Satisfactory answer

Last Saturday, my mother took me to a flower shop. When I arrived at the flower shop, there were flowers everywhere, and the fragrance of flowers could be heard from time to time. It was really marvelous! At this time, my eyes moved to the small mimosa in the corner. Among those tall green plants, it looked so small. I had an inexplicable affection for it. Before I left, I asked my mother to buy the little mimosa.

When I got home, I couldn't wait to see how shy it was. The leaves of Mimosa are green and composed of dozens of tiny leaves, like a weaving shuttle. There is a leaf stem connecting the leaves in the middle, stringing together the tiny leaves. There are small thorns on each branch. If your hand accidentally touches it, it will pierce and bleed. Mimosa is really like a shy little girl. I touched its leaves lightly, and it closed along the petiole, and the leaves became very thin. At the same time, the branches also lowered their heads, as if they did not dare to It's like meeting someone. What fun! I'll fiddle with it when I have time.

But one time, I went to play with the mimosa again, but I found that the leaves of the mimosa moved much slower. I kept fiddling with it, and eventually the mimosa stopped moving at all! Is it dead? But it made me anxious.

I immediately read "One Hundred Thousand Whys" and finally found the information and understood the mystery: It turns out that there is a soybean capsule called a leaf pillow under the petiole of Mimosa pudica, which contains sufficient water. When you touch the leaf with your hand, the water in the leaf pillow immediately flows elsewhere, the leaf pillow deflates, and the leaf hangs down. I often touch it continuously, and the water in the leaf pillow is gone. When there is no time to replenish new water, the leaves will not move.

I didn’t expect that a small piece of grass could hide such interesting knowledge. It seems that we need to observe more in daily life!
