Chapter 1: Observing Mimosa

I went to learn guitar on Friday. On the way back, I saw some mimosa on a flower stall. I liked it very much, so I bought it. A basin.

When I got home, I put it on the table and took a closer look. The leaves of Mimosa looked very strange. There were a row of leaves growing symmetrically on one stem. Surprisingly, there was no mold. It actually makes its leaves grow so symmetrically that the leaves on both sides can completely overlap, and the symmetrical leaves on both sides are the same size. Each stem is thin, but strong enough to hold a mimosa leaf. And I was surprised to find that the back of the leaves of Mimosa was purple. Purple contains green, like a shy person wearing a purple veil. It really lives up to the name Mimosa.

It is said that if you touch the mimosa with your fingers, the leaves of the mimosa will slowly close. I curiously touched a handful of mimosa leaves. Those leaves were originally wide open, and I After touching it, it seemed to slowly shrink up. At first, the two leaves at the front immediately closed, and then the leaves at the back came together shyly like a shy little girl one after another. Finally, these leaves All put together, they become one line. I thought it was fun, so I touched all the leaves again, so they all closed into one long leaf.

Why do the leaves of Mimosa close when you touch them? I checked on the computer and found out that there is an enlarged organ called the "leaf pillow" at the base of the petiole of Mimosa pudica. There are many parenchyma cells growing in the leaf pillow, and these cells are very sensitive to external stimuli. Once the leaf is touched, the stimulus is immediately transmitted to the leaf pillow. At this time, the cell fluid in the parenchyma cells begins to flow into the intercellular space, which reduces the expansion ability of the cells. The pressure between the cells in the lower part of the leaf pillow is reduced, resulting in leaf closure and petiole closure. The phenomenon of sagging. After 1-2 minutes, the cell fluid gradually flows back to the leaf pillow, and the leaves return to their original appearance. After reading this information, I realized that this is the origin of the name Mimosa!

The purchase of mimosa this time not only allowed me to understand the appearance of mimosa, but also the origin of its name. I gained a lot. Chapter 2: Observing Mimosa

There is a mimosa clump in the garden downstairs of my house, and the pink flowers are very beautiful. In fact, we can see mimosa in many places. It is a plant that is found everywhere, but because it is small, we rarely notice it.

We all know that if you touch the leaves of Mimosa with your hands, it will immediately close the two leaves and then hang down, just like a shy little girl lowering her head. This is where the name Mimosa comes from. Do you know why it is "shy"? In fact, it is because when the leaves of Mimosa are stimulated, they are immediately transmitted to the petiole, and the petiole will retract the leaves, so the two leaves will close. Then the stimulation is transmitted to the stem, and the stem will shrink when stimulated, so the leaves will be lowered. Hang down. If we keep touching the leaves of the mimosa, the mimosa will feel "bored" and it will no longer close the leaves. Isn't it interesting?

In fact, the flowers of mimosa are also very special. The flower of Mimosa is a flower ball composed of many small flowers. Each small flower has four petals and several stamens. So when the mimosa blooms and bears fruit, many pods will grow on its flower bulbs. After the pods fall off, countless holes are left on the flower bulbs.

Mimosa is not only "shy", it is also a special plant.

Chapter 3: Observing Mimosa

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 wonderful. ! 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, with 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. The leaves became very thin, and the branches also lowered their heads, as if they didn't 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 piece of grass could hide such interesting knowledge. It seems that we need to observe more in daily life! Chapter 4: Observing Mimosa

I heard that the leaves of Mimosa will close as soon as you touch it. I was very confused about this and planned to test it myself and confirm it.

On Sunday, I went to the medicinal plant area of ??the Fairy Lake Botanical Garden and saw a cluster of mimosa under a cluster of fiery red cockscombs. Its leaves were green and green. I touched it gently. The leaves, and sure enough, I found that the leaves slowly closed and hung down. I touched it suddenly again. The leaves quickly closed and hung down. After about 5 minutes, the leaves opened again. It's really strange. Why is this? Woolen cloth?

After I got home, I immediately looked up information on the Internet, and finally solved the mystery for me: It turns out that at the joint of the Mimosa petiole, there is a bulging bag called a leaf pillow, which is full of water. , is particularly sensitive. If something touches the leaves, the leaves will hang down. At this time, the mimosa will have no energy at all. No wonder I touched it gently with my hand, and it lowered its head like a shy little girl. It is also said on the Internet: Mimosa pudica, also called Mimosa pudica, likes full sunlight and likes to grow in moist soil, and is not cold-tolerant.

This observation of mimosa is really interesting. It also taught me that as long as we carefully observe and think about the things around us, interesting things are close at hand, and we can also discover the mysteries of life! Chapter 5: Observing Mimosa

I used to see Mimosa on the slopes of Jiulong Mountain in my hometown. My parents said that this plant is a perennial herb, but it does not look like other herbaceous plants. So weak.

The flowers of Mimosa are very special. It has purple or pink flower balls, which are not actually one flower, but a collection of many small flowers. If you accidentally separate a small unit on the earth, you can see that each small unit has four-split petals and four long stamens. It turns out that each small unit is its flower.

But why is this plant called mimosa? Oh, it turns out that if you touch it lightly, its open pinnate compound leaves will immediately close, and then the whole leaf will hang down again, showing "shyness". This is because the plant is stimulated and shaken. a reaction. The positive reaction is called perceptual movement in biology, which is the result of changes in cell tension after Mimosa is stimulated.

Judging from previous observations, I still gained a lot today. At least I understand why Mimosa is called Mimosa and how it is "shy".

The mimosa is also very green, and also green with a hint of green. Chapter 6: Observing Crickets

On an autumn night, I lay quietly on the bed and listened. The sound of the crickets playing excited me and excited me. It was clearly a beautiful piece of music. Let my heart be filled with fantasy. So I pestered my father to take me to catch crickets. Dad couldn't resist me, so he took me to the grass beside the river downstairs in the community and started the capture operation.

We heard the cry of "cricket cricket" in a pile of rocks. I asked my father: "Why can I only hear the cry of crickets but no crickets?" "Don't talk, it will." Under that red brick, Dad whispered. Following the cry, we tiptoed close to the "target". Dad held the prepared mesh cover in one hand and gently lifted the brick with the other. I stood aside and stared intently. I saw the crickets struggling desperately in the net under my father's net, as if to say: "Let me out, let me out." We put the caught crickets in the small jars with soil that we had prepared in advance. Here, raise her like a baby.

Crickets, also known as crickets, are aggressive and playful insects. It has a suit of black armor, a pair of long tentacles, a pair of thin wings that are purple-brown and smooth, six fat legs that are good at jumping, and two sharp teeth, which are sharp weapons when fighting with the same kind. .

The cricket started to be very afraid of me. When it saw me approaching, it immediately retreated behind the jar, swung its tentacles at me, stared at me with its two big teeth, and retracted its hind legs inward. Looked very nervous. After a while, seeing that I had no intention of harming it, it slowly started to spread out in the small jar, but it still stopped to look at me from time to time. I became very interested in it and wanted to know more about it. I took a piece of fur grass to tease it, and it was like a general, shouting very mightily, as if to say: "Go away, this is my territory, don't disturb me!" Haha, it's really the only one. Personality guy.

The biggest characteristic of the cricket is its cry, "cricket cricket", which is like a musician singing. I found that when crickets sing, their wings keep waving. Why is this? I ran to ask my dad. Dad told me meaningfully; "The singing of crickets is produced through the friction of wings." It turns out that the secret of crickets singing lies in their wings, and I suddenly realized it.

The fun and singing crickets brought endless fun to my National Day holiday! Chapter 7: Observing Mimosa

I have always felt that Mimosa is very magical, because it is a shy grass! A few days ago, my father gave me a surprise - he bought me a pot of mimosa to satisfy my curiosity.

The leaves of Mimosa are in bunches and look like one large piece, but if you look closely, you will find that it is composed of many small leaves, which are laid out in pairs on the stem. , in opposite directions, like two good friends holding hands and playing. Its tender red stems set off the bright green leaves, just like a simple and elegant girl, so beautiful!

Mimosa is very interesting. As long as you touch its leaves with your hand, it will order the bunches of leaves to close up, like a shy girl, and like it wants to reveal some ulterior secrets. Just hide it. Why does Mimosa behave like this? Is that how it got its name? When I was puzzled, grandpa came over. I told my question to my grandfather, and he smiled and said, "What a studious child!" He touched my head with his hand and said, "There is a lot of water in the leaves and petioles of Mimosa pudica. When it is exposed, the water in the leaves will flow to other places, and the leaves will curl upward because of the loss of water. On the contrary, if you touch the petiole, the water below will flow away, and the leaves will hang down. "

"Wow! Grandpa, you are so awesome, you know so much!" Grandpa smiled slyly. It turns out that when the mimosa is shy, it not only curls up, but also sometimes hangs its head.

I returned to my room with a sudden realization and suddenly caught a glimpse of "A Hundred Thousand Whys" on my bookshelf. I opened the catalog and found the question "Why is Mimosa shy?" I immediately opened the answer book to check, and what the book said was the same as what my grandfather said! It turns out this is grandpa’s secret! In the book, I also learned that the shyness of Mimosa is a skill to protect itself. It is not only shy when touched by hands, but also becomes shy whenever it encounters strong wind or heavy rain.

It turns out that there is a lot of knowledge around me. I must study hard and discover the beauty around me! Thank you so much dad for the surprise! Chapter 8: Observing Mimosa

Today I observed the mimosa in front of the window.

Mimosa is a plant that likes sunlight very much. It is about 60 cm tall. The side of the stem facing the sun is purple, while the side facing away from the sun is green. There are many small thorns on the stem and many small hairs. The green leaves grow neatly to the left and right, and the open leaves are shaped like a fan. If you touch it lightly, the leaves will shrink immediately, and the leaf stems will lower their heads. It really looks like a shy little girl, and It seems that the protective device has been activated, more like a ticklish child. Whenever this happens, I especially like to play with it. Touch it left and touch it right. It is really fun.

Mimosa will also bloom and bear seeds. The flower buds are like mini pine cones, growing at the top of the stem. The flowers are small pompon balls, and the seeds are like small peas.

There are many secrets in plants in nature, waiting for us to observe carefully and understand deeply, so that we can make good use of them. ;
