It is always said that lotus flowers come out of the mud but are not stained, why do they come out o

Lotus leaf self-cleaning effect.

Using things as a metaphor for people, praise some people for not being affected by the environment around them and people and still living elegantly and freely.

Cause. Lotus leaf self-cleaning effect.

As we all know, water droplets falling on the lotus leaf will become a free-rolling water droplet, which shows that the lotus leaf surface has strong hydrophobicity, and the water sprinkled on the leaf surface will automatically gather into water droplets, and the rolling of the water droplets will adsorb the dust sludge falling on the leaf surface and roll out of the leaf surface, so that the leaf surface is always kept clean, which is the famous "lotus leaf self-cleaning effect (lotus-effect)".

The microstructure of the lotus leaf.

After long-term observation and research by two German scientists, the mystery of the lotus leaf surface was finally unveiled in the early nineties of the last century. The self-cleaning effect of lotus leaves is related to the microstructure of the surface of lotus leaves. It turns out that there are very complex multiple nano- and micro-scale ultrastructures on the leaf surface of lotus leaves.

Under a super-resolution microscope, it can be clearly seen that there are many tiny papillae on the surface of the lotus leaf. The average size of the mastoid is about 10 microns and the average spacing is about 12 microns. Each papillae is made up of many protrusions about 200 nanometers in diameter.

For example, the leaf surface of the lotus leaf under the electron microscope seems to be covered with a "small mountain bag" that rises one after another, which is covered with fluff, and a steamed bun-shaped "bunker" convex top grows on the top of the "small mountain bag", as if the antennae protect the leaf surface, so that things larger than it cannot get close to the leaf surface at all.

The mystery of the self-cleaning effect of lotus leaves.

The presence of this milky structure fills the hollows between the "mountain packs" with air, thus forming a very thin, nano-thick layer of air that clings to the leaf surface. As a result, the dust and rain, which are much larger in size than this structure, can only form a few points of contact with the convex roof of the "mountain bag" on the leaf surface after falling on the leaf surface, separated by a very thin layer of air. The raindrops form a ball under the action of their own surface tension, and the water balls absorb dust and roll out of the leaf surface in the rolling, which is the mystery of the "lotus leaf effect" that can clean the leaf surface.

In fact, this complex ultra-micro and nano structure of plant foliage is not only conducive to self-cleaning, but also conducive to preventing the invasion of plants by various harmful bacteria and fungi floating in the atmosphere. In addition, and more importantly, in order to improve the efficiency of the foliar absorption of sunlight, and thus improve the photosynthesis of the leaf chloroplast.

Because of the environment in which the lotus is located, she is neither far away from pollution, but also "in the same stream" and not willing to "bend the knot", but this will appear more clean.

Because the lotus plant will not be attached to the silt, it will come out of the silt without staining.

Because there is an external cause, water, there is water, so there is no contamination! Without water, it will naturally carry mud with it, or it will die. Nothing exists in isolation, so is that all things in nature and so are people who are part of nature!

The lotus flower is not stained by silt, which may still be related to the growth environment of the lotus itself and the plant itself.

Because the lotus itself is on the lotus root, it can keep itself clean.

Because he keeps himself clean, doesn't follow the crowd, and keeps himself in his own state all the time.

Because it grows in silt, but the lotus flowers that bloom do not have silt.

Because although his river is full of silt, it is not in the silt at the moment it blooms.

I think it's because lotus roots grow in silt, while lotus flowers are not only clean but also beautiful.

Because this is the unique attribute of the lotus, and it is also the reason why the ancient literati and ink writers liked it.

Because flowers love to be clean! Don't let the dirt get on your body!

Maybe the effect on the lotus is similar to that of a waterproof nano.

The lotus flowers reflect the red sun, and the lake scenery is as green as blue. Yujie flowers are fairy, who competes in summer?
