Mimosa

Today, my mother and I went to my favorite place to go - the flower and bird market. As soon as I got there, I hurried to find a place to sell mimosa, and a small pot of mimosa was placed there in a small stall. I touched it gently with my fingers, and the mimosa quickly closed the leaves, like a shy little girl. I like mimosa very much, but I never know why it is "shy".

So, when I got home from the flower market, I went to check the information about mimosa. The original skill of mimosa is the result of adapting to the environment. Mimosa is produced in Brazil in the Americas. In such a tropical region, plants are often attacked by storms. If mimosa can't close the leaves when they are in danger, let the petiole hang down, then it is delicate. The leaves will be ruthlessly ruined and difficult to survive. The most sensitive part of mimosa is the leaf pillow. Here, it is full of water and maintains a lot of pressure. When the mimosa is touched, the water in the cells below the leaf pillow will flow out to the upper and the sides. Then, the upper part of the leaf pillow will bulge, and the lower part will squat down, and the petiole will hang down.

Mimosa is fun, but you can't put it in the bedroom, because people often touch it, it will be harmful to the body.

I finally knew the secret of mimosa. There is no such thing as a big world. I have to study hard and master more knowledge in the future.
