What will happen if you touch the mimosa before it rains?

What will happen if you touch the mimosa before it rains? If you touch the mimosa, its leaves will shrink slowly, droop slowly, and even open again after a little closing, which indicates that the weather will turn from sunny to cloudy or it will rain soon.

What happened to the mimosa before it rained? There is nothing wrong with raindrops not hitting the leaves, unless the leaves close slowly because it feels dark. Once the raindrops hit the leaves, the leaves will close quickly.

Can mimosa be poisoned if touched occasionally? number

Mimosin o-β-D- glucoside is slightly toxic. Long-term contact or taking can make hair follicles in skin cells decline, thus making hair and eyebrows yellow or even fall off. Mimosa is a little toxic and can't be taken alone. It should be used together with other drugs. In addition, due to mimosin, it can also cause cataracts and growth inhibition. And people who eat mimosa will lose their hair, so it is not suitable for planting mimosa indoors.

What are mimosa afraid of? How to keep mimosa from closing when touching? How to breed mimosa better? Mimosa is easy to feed, not so delicate. I used to grow a lot when I raised it at home. Why don't you turn it off when you meet it? Isn't it the characteristic of mimosa, otherwise it will be different from other flowers and plants.

What about the mimosa before touching it? What about after touching it? Before touching the mimosa, the leaves are stretched, after touching, they are closed, and then the stems become soft.

If you met a mimosa, what would you say? What will mimosa say? When I meet a mimosa, I will say I'm sorry. I broke your arm and leg too hard, and the mimosa will answer me. I only hid my hands and feet because of your handsomeness.

Why do mimosa touch each other and get together? It turns out that there is an enlarged organ called "leaf pillow" at the base of the petiole of mimosa, and there are many parenchyma cells in the leaf pillow, which is very sensitive to the outside world. Once it touches the leaf, * * * will immediately spread to the occipital, at this time, the cytosol in parenchyma cells begins to flow to the intercellular space, which reduces the expansion ability of cells, reduces the intercellular pressure at the lower part of the occipital, and leads to the phenomenon of leaf closure and petiole drooping. 1-2 minutes later, the cell fluid gradually flows back to the leaf pillow, so the leaves return to their original appearance.

The above phenomenon of Mimosa leaves is a physiological phenomenon, and it is also the result of Mimosa adapting to the external environment for a long time in the process of system development. Because the mimosa originated in the tropical region, where there are many storms, when the storm blows the leaflets, it immediately closes the leaves to protect them from the storm, thus gradually forming this physiological phenomenon.

Why do the leaves of mimosa close at the touch? Mimosa is a perennial herb, but it is not as weak as ordinary herbs. Its stem branches from the basal part, which is upright or inclined, about 20 to 50 cm high, all with long soft hair and sharp thorns. The leaf is palmately compound and consists of four pinna. There are many small leaves on each feather, which is different from ordinary palmately compound leaves. There is an enlarged structure at the base of the total petiole, which is called "leaf pillow" near the base of the petiole.

The flowers of mimosa are very special. Its purplish red or pink flower ball is actually not a flower, but an inflorescence composed of many small flowers. If you carefully separate each small unit on the ball, you can see that each small unit has four divided petals, four long stamens and a pistil. It turns out that every small unit is its flower.

After the flowers of mimosa are in full bloom, most of them will form pods, so the mimosa fruits we see are also densely spherical. Each pod has three or four nodes and the surface is hairy. When the pod matures, it falls off from one section to another, leaving only the empty shelf formed between the sections, which looks very interesting.

If you touch it gently, its open pinnate compound leaves will close immediately, and then the whole leaf will hang down again, showing a "shy" appearance, hence the name mimosa.

Why do mimosa droop when we touch it intentionally or unintentionally?

Mimosa, the phenomenon of closed leaves and drooping petioles, is not "shy", but a response of plants to * * * and vibration. This reaction is called nasal movement in biology, which is the result of cell tension changes after mimosa is exposed to the outside world.

It turns out that the leaves and petioles of mimosa have special structures. There is a relatively enlarged part on the petiole and leaflet base of compound leaves, which is called leaf pillow. Leaf pillow is the most sensitive to * * *. Once it touches the leaf, * * * immediately spreads to the leaf pillow at the base of the petiole, causing two small leaves to close, and the contact force is strong, not only to the leaf pillow of the lobule, but also to the leaf pillow at the base of the petiole soon, and the whole petiole droops. Why is this happening? This is because there is a large vascular bundle in the center of occipital bone, which is surrounded by parenchyma and has many intercellular spaces. When the vibration is transmitted to the occipital lobe, the cellular fluid in the parenchyma cells in the upper part of the occipital lobe is discharged into the intercellular space, which reduces the swelling pressure of the cells in the upper part of the occipital lobe, while the original swelling pressure is maintained in the lower intercellular space. As a result, the leaflets stand upright, the two leaflets are close together, and even the whole leaf hangs down. It has been studied that mimosa leaves will close within 0.08 seconds after being subjected to * * * *. After * * *, the transmission speed is also very fast, and the highest speed reaches 10 cm per second. * * *, after a short period of time, everything slowly returned to normal, the lobules unfolded again, and the petiole stood up. The recovery time is generally 5- 10 minutes. But if we continue to tease and repeatedly tease its leaves, it will feel "bored" and no longer respond. This is because the continuous * * * makes the cell fluid in the occipital lobe cells lose, which can not be replenished in time.

This special skill of mimosa has its historical roots. Its hometown is Brazil in tropical South America, where there are often strong winds and heavy rains. Whenever the first drop of rain hits the leaves, it immediately closes the leaves and hangs down the petiole to avoid the damage of the storm. This is an adaptation to changes in external environmental conditions. In addition, the movement of mimosa can also be regarded as a way of self-defense. When the animal touched it lightly, it closed the leaves, and the animal dared not eat any more.

Mimosa is not a native of Taiwan Province Province, but its hometown is far away in South America. Taiwan Province Province was introduced by the Dutch in the17th century, and now it can be seen in open spaces, riverbeds, wasteland, playgrounds and other places all over the province. Especially in central and southern China.

If the mimosa doesn't close, touch it. If you touch it frequently, its stress response will be weakened until there is no response, and it will appear again after a while.

Will you be all right if you are stung by a mimosa? Mimosa is poisonous, but gentle. Don't worry, no problem. Don't worry, you can disinfect it.

Please adopt it. Thank you.
