There is a mimosa in my balcony. It is not strange. But when I touch it with my hand, the open leaves suddenly respond and gradually close. After a while, the closed leaves gradually open. I wonder why Mimosa can react like an animal?
I checked the information on the Internet and finally found the answer: the reason why the leaves of Mimosa pudica close when touched by people is that the "swelling effect" of Mimosa leaves is at the base of the petiole of Mimosa pudica, which has a water filled parenchyma pillow. As soon as the Mimosa is touched to make its leaves vibrate, the lower part of the pillow will shrink like a leaky tire, the upper part will bulge like a full inflated ball, and the petiole will droop and close. When the pillow of Mimosa pudica is stimulated to close, it will produce a kind of bioelectricity, which will transmit the information to other leaves, and the other leaves will also close in turn. When the stimulation disappears, the pillow will be filled with water gradually, and the leaves will open again to restore their original shape. Therefore, with a touch of our fingers, it will shrink.
Originally, the small Mimosa also hides the huge secret, really wonderful! There are several Mimosa plants in the flower bed next to the mother's factory of Mimosa. I was curious because of its difference, so I paid special attention to it.
In spring, Mimosa sprouts, the leaves are tender green, very lovely. In summer, Mimosa branches and leaves are lush, leaves are very strange, one root thin stem, there are some thin needle like things on both sides, and the leaves of Metasequoia are very similar. In autumn, Mimosa blooms, one after another small flowers fluffy, there are pink, purple. Although it is very small, insignificant, but when you observe it carefully, you will feel that it is beautiful and lovely, it is a kind of delicate beauty, very popular. Late autumn and early winter, Mimosa bearing fruit, fruit like lentils, outside a layer of green shell, inside is the seed. After a period of time, the shell turned brown. Soon, the seed jumped out of the shell and fell into the soil. Next spring, it would take root and sprout, and it would continue to reproduce from generation to generation. It's just like other plants.
What makes people wonder is that when I touch it, the leaves will droop and close? I couldn't understand it, so I had to search for information online.
It turns out that there is an expanded organ called the leaf pillow at the base of the petiole of Mimosa pudica. There are many parenchymal cells in the petiole of Mimosa pudica, which are very sensitive to external stimuli. Once the leaf is touched, the stimulation is immediately transmitted to the leaf pillow. At this time, the cell fluid in the parenchyma cells begins to flow to the intercellular space, which reduces the expansion capacity of the cells, and the pressure of the cells in the lower part of the occipital decreases, resulting in the phenomenon that the leaves are closed and really drooping. After 1-2 minutes, the cytosol gradually returned to the pillow, and the leaves returned to their original appearance.
I love this wonderful Mimosa! There are beautiful pink flowers in my house. In fact, we can see Mimosa in many places. It is a kind of plant that can be found everywhere. But because it is small, we seldom notice it.
We all know that if you touch the leaves of Mimosa with your hand, it will immediately close the two leaves and then drop them, just like a shy little girl bowing her head, which is the name of Mimosa. Do you know why it's shy? In fact, when the leaves of Mimosa pudica are stimulated, they are immediately transmitted to the petioles, and the petioles will fold up the leaves, so the two leaves will close, and then the stimulation will be transmitted to the stems. The stems will shrink when stimulated, so the leaves will droop. If we keep touching the leaves of Mimosa, Mimosa will also feel "bored", it will not close the leaves. Isn't it interesting?
In fact, Mimosa flowers are also very special. Mimosa is a flower ball composed of many small flowers. Each flower has four petals and several stamens. So when Mimosa blooms and bears fruit, it will grow many pods on its flower ball. After the pod falls, countless holes are left on the flower ball.
Did not expect that Mimosa will not only be "shy", but also a special plant! Today, my mother and I went to Yuquanying flower market together to finish the homework assigned by the teacher to buy Mimosa. As soon as I entered the door, I saw many Mimosa plants. After repeated observation and comparison, I finally chose a basin of lovely Mimosa.
My mother and I happily went home and put Mimosa on the balcony. The leaves on the twigs of Mimosa pudica are only a little bit like rice grains, which are opposite to each other, like feathers. The color of the old leaves of Mimosa pudica is dark green, but the new leaves are light green. Mimosa has 20 cm tall branches and only 4 cm short branches. It is full of spring in the sunshine.
I gently touch the tip of the leaf, the leaves close in turn, like a shy little girl. It's said that a heartless Chinese turned into mimosa and bowed his head to admit his mistake. This is just a legend. In fact, the water on the leaves is stimulated and flowed away. The leaves droop down. When there is no threat, the leaves will open. This is a skill of self-protection. This is really an interesting plant.
I go to visit it every day, hoping that it will grow up soon and bloom beautiful flowers. The wonderful Mimosa granny raised many flowers, including the vibrant dripping Guanyin, the verdant Chlorophytum, the fragrant camellia, the delicate cockscomb, and the cactus and cactus. But my favorite is the petite Mimosa.
This basin of Mimosa is not high, but it is so vigorous. Its leaves like a piece of feathers, edge and vein have sharp spines, like a few living villains with a sword in defense of the country. Its brown fruit is flat and flat, the edge and leaves are the same, have hair, feel itchy. Its flowers, like a small pink ball, a gust of wind, the small pile slightly shaking, very popular.
Mimosa is resistant to drought but not cold. It likes to grow in the warm sunshine, not in the cold season. Therefore, every spring, grandma will plant its "children" soil, put it in the sun shining place, regularly go to water it. Before long, it will sprout, and then gradually grow stems and leaves, and after a while it will bloom. In the autumn, it withers after giving birth to "children".
It is placed on the windowsill, is not only a good ornamental plant, but also one of my most interesting friends! In the summer, it worked hard to grow, put on a emerald green clothes, I gently touched it with my hand, it was like a shy girl, the leaves immediately closed up, the stem also slowly down. After a while, it was bold again and opened its leaves with air, as if to say: "who is more beautiful than me? Look, look! How green my clothes are
