How to write 300 words in mimosa's composition

A few days ago, my mother bought a pot of flowers and plants, which looked ordinary. I was surprised, but my mother mysteriously told me that this is the mimosa, which is amazing! What is the magic of this seemingly ordinary grass? I can't help wondering. One day, I finished my homework and looked at the green leaves of mimosa, always wanting to explore its magic. However, it is a mystery. Inadvertently, I touched its leaves. Oh, something strange happened: I saw the leaf I touched gradually close and shrink into a ball. Like a little girl who covers her face with a veil, she is very shy.

So, I wonder if there is water shortage? On closer inspection, the soil in the basin is wet. It's not water shortage, then what's the reason? I went to ask my father, and he simply said, "I don't know! Your mother may know! " I turned to ask my mother again. My mother smiled and said mysteriously, "You should take a closer look."

I went back to the living room and looked again. The whole mimosa stood upright in the flowerpot. The leaves I touched also scattered.

I jumped for joy! So this is the magic of mimosa! I finally discovered the secret of mimosa!
