1. Write a composition on mimosa
I like the simple and elegant lily, and I also like the coquettish rose, but my favorite is the obscure mimosa.
The mimosa in spring is like an innocent little girl. It grows a small green leaf almost every other day. In the spring of April, the mimosa is covered with small leaves, which are neatly arranged on both sides like a ladder. In May, the leaves of Mimosa become larger, and one Mimosa plant resembles a fan. Every day, I can't help but touch the mimosa. Whenever my nails touch its leaves, the leaves shrink in shyly.
In summer, the green leaves of Mimosa become darker and the leaves of Mimosa become lush. What’s even more attractive is that the mimosa blooms with pink, cute, round flowers. Next to the flowers there are buds waiting to open. Next to the bud, there are three small flowers close together, like three inseparable good friends. The stems underneath the flowers have thin, pointed thorns. I tried to touch it, but the little thorn was very stinging.
In autumn, mimosa bears fruit, and its fruits are connected one by one. It looked like he was wearing a transparent and thorny dress. After a week, all the fruits fell to the ground. At first I thought it was a useless thing, so I threw it into the dirt.
It was winter, and three mimosa plants grew in the soil. At that time, I thought to myself: I would have known better not to throw away the fruits. But now, there is no hope.
Do you know why mimosa is shy? The reason for this kind of opening and closing is that there is an enlarged part called the "leaf pillow" at the base of the petiole of Mimosa pudica. There are membrane cells in the leaf pillow. When the leaf is touched by the outside world, the vibration is transmitted to the leaf pillow. At this time, the membrane cells The intracellular fluid immediately flows to the intercellular space and reduces the expansion ability of the cells. The leaves automatically closed, and the petioles and twigs drooped at the same time. After a few minutes of "calm conditions", they returned to their original state. Now you know it!
Mimosa is not only used for ornamental purposes, it is also used as medicinal materials and for predicting earthquakes. You see, this kind of grass is perfect! 2. A composition describing the plant Mimosa
There is a mimosa planted at my house. It has bloomed now. The color of the flower is lavender and the shape is spherical, very beautiful.
Mimosa is a very thin grass with feather-like leaves, fluffy flowers, and cute little pods. The most interesting thing is that as long as you touch its branches and leaves lightly, it will close its leaves and droop its leaves like shyness. This is the origin of its name.
I plant many flowers at home, including roses, chrysanthemums, and roses, but my favorite is the mimosa.
There are newly grown leaves of Mimosa pudica and those that have been growing for a long time. The newly grown leaves are green and face each other. I heard from the science teacher that this kind of leaves is called opposite. The leaves that have been growing for a long time are dark green, like a string of small green firecrackers, and the petiole should be the fuse. I looked carefully and found that there were small thorns on its stems. They looked fluffy, but if they were accidentally pricked, they would feel pain. Its flowers are pink, like a small hair ball, but why is such a beautiful grass called this name?
I felt very strange, so I ran to ask my dad, and my dad said: "You will know if you touch it." I tried it as my dad said, and I saw the mimosa immediately closed its leaves. . Hey, she really looks like a shy little girl. I finally understand, but why does it close?
I thought about it again and again, but still couldn’t figure out why this happened, so I went to find a teacher who couldn’t speak - Shu. As soon as I read the book, I realized that there is a leaf pillow at the base of the Mimosa petiole, and the leaf pillow is full of water. When you touch the leaf with your hand, the leaf vibrates, and the water in the leaf pillow immediately flows to both sides, so that the petiole droops and closes.

I heard that Mimosa is a shy little girl. When touched, it will shyly lower its head, but why is that? With a curious and expectant heart, I went to the plant store and bought a mimosa, took it home, and put it on the balcony to take good care of it.

I touched it gently with my hand, and the mimosa really closed its leaves like a shy little girl. About 30 minutes later, the leaves of the mimosa opened. I'm excited because the trial worked. However, I still have some doubts: Why does the mimosa close up when touched? I ran to ask my mother, and she said: "Because mimosa originally grew in South America, where there are often storms and there are many bugs. In order to protect itself, it will close up as soon as something touches it." My mother also told me that , according to the research of scientists, it was found that mimosa also has the function of protecting against earthquakes!

The parenchyma cell tissue, the leaf pillow, is filled with water. When a person touches the mimosa with his hand, the leaf vibrates, and the water in the cells in the lower part of the leaf immediately flows to the upper part and both sides, so that the leaf looks like it is deflated. The ball relaxes. What an interesting phenomenon! (2) After school in the afternoon, I ran all the way home. There was a lot of homework today. If I didn’t hurry up and write, I wouldn’t have time to watch TV in the evening. Because I was in a hurry, I accidentally touched the mimosa that my mother bought newly. In an instant, , I felt itchy on my calves. I looked back and saw a pot of mimosa looking up at me. I ran to it and looked at it carefully: the leaves were about half the size of my fingernails. The left one and the right one are on the stem, which is so cute. Suddenly, its leaves stick close to each other, like a graceful girl. I don’t know how long it took, and its leaves opened again.
