Flowers in nature are all colorful, why are there so few black ones?

Light is a type of energy that, when absorbed by an object, heats up (basks in the sun), a phenomenon known as the thermal effect of light. The petals are delicate and delicate, and it is necessary to select the color light absorption with weak thermal effect to preserve and reflect the color light with strong thermal effect. Sunlight is made up of seven colors:

Red, orange, yellow, green, blue, indigo, purple. Therefore, in nature, there are more safflowers, orange blossoms, and yellow flowers, less blue indigo flowers, and purple flowers, and very few green flowers (rare treasures, green peonies are more precious). In nature, living things evolve according to the law of natural competition, with the fittest surviving and the unfit eliminated.

Plants evolved flowers to fertilize and produce seeds to reproduce. Fertilization methods include self-pollination and cross-pollination.

All self-pollinating plants do not depend on other organisms, the flower color is not necessary, and the branches and leaves are also different, and green is the majority, such as wheat, soybeans, etc. Cross-pollinated plants, in order to attract insects for pollination, must use special colors, smells or smells, honey, etc. to attract insects. Generally speaking, the flowers that bloom and pollinate during the day are mostly bright flowers such as red, purple, yellow, and blue, such as peonies, morning glories, etc., but many have no fragrance because they cannot rely on fragrance.

The flowers that bloom and pollinate at night are mostly white or yellow. If you have evening primrose or evening primrose, because it is not easy to distinguish the color, as long as it is bright, it is fine, but the taste is important.

Most of them have a strong smell, depending on what insect they attract. Black flowers are ugly both day and night. So, not many plants have evolved black flowers.

Humans nurture flowers and plants according to their preferences, regardless of the feelings of the plants. They breed flowers of any color, so they develop black flowers such as black tulips, black roses, and black peonies. This is not natural selection, but artificial selection.

Nature's colorful flowers often make us linger, and each flower color has its own unique charm. Have you seen so many flowers, have you ever seen a black flower? Are there black flowers in nature?

Why are black flowers rare? Why do flowers have color? Assisted reproduction to attract insects for pollination.

Plants are actually very smart, every part of them is useful, and the most attractive thing about a flower is its petals. Flower petals cannot be used for reproduction or nutrition, so why did plants evolve petals? Because plants need the bright color of their petals to attract insects, pollinate them, and help them reproduce.

Insects are attracted to bright colors and smells, and some flowers function on their petals instead of evolving scents.

Because colorful flowers can attract small bugs to help pollinate and are more conducive to reproduction, black flowers are difficult to reproduce, so there are few black ones.

In fact, there are no pure black flowers in nature, but some are close to black or similar to black, why are there so few black flowers? Because black can absorb all the waves of sunlight, it is almost impossible to reflect the light waves with higher heat in the sun, such as red, yellow, and orange waves, so black means being burned, or even death, and the flowers themselves have the ability to protect themselves, so they naturally seek advantages and avoid disadvantages when growing. So it's hard for us to see pure black flowers in reality.

According to relevant reports, as well as expert investigations, due to the action of light waves and heat, black flowers will easily absorb light waves, resulting in damage to their tissues.

In fact, black flowers are very rare in nature, especially the real black flowers do not exist, the main reason is that black flowers can absorb all the light waves in the sun, and the temperature rises quickly in the sun, and the flower tissue is easily damaged. Therefore, we often see red, yellow, orange, white and other color flowers, this is because these flowers can reflect the red, orange and yellow light waves that contain more heat in the sun, to avoid its burning delicate flowers, which is a kind of self-protection effect of plants. Black flowers, on the other hand, do not have this ability, so they are gradually eliminated in the long process of evolution.

So the black flowers we see are actually crimson or deep purple flowers that are close to black, that is, what we call "red purple, purple black" in daily life, black peonies, black tulips, black chrysanthemums, and black roses.

Secondly, the black color is inconspicuous and not easy to be found by insects, which reduces the possibility of insect pollination, and it is easy to be eliminated by natural selection.

In nature, there are thousands of purple and red flowers, but there are no pure black flowers.

Because the color of the flower is determined by the anthocyanins and conditions such as light, temperature, nutrients and water. When the plant cell liquid pigment is acidic, the flowers are red, and the stronger the acidity, the redder the color; Whereas, when the cytofluid pigment is alkaline, the flowers are blue, more alkaline, and blue-black, while when the cytochrome is neutral, the flowers are purple, and if the cytochrome does not contain pigment, the flowers are white.

Most of the flowers you see are red, yellow, orange, and white, because these flowers can reflect the red, orange, and yellow light waves that contain more heat in the sunlight to avoid being burned. If the flower is black, because the black absorbs all the light waves in the sunlight and heats up quickly in the sun, the flower tissue is damaged and withers quickly, and the flower loses its proper reproductive instinct and cannot produce black offspring.

There are also some black flowers in nature, like black tulips, black peonies, black roses, black iris, black chrysanthemums, etc., but those are not pure black, but darker purple or red.

Without melanin, black flowers would certainly be gone.

Some. Black tulip is one of the flower colors of the lily family tulip, which was cultivated by three students from the Singapore Polytechnic in early February 2005, commonly known as the "Queen of the Night", and is one of the rare tulip varieties, which is still rare in the market.

Due to the climate of the Mediterranean, the formation of tulips adapt to the characteristics of wet and cold in winter and dry and hot in summer, its characteristics are dormant in summer, rooting and germinating new shoots in autumn and winter but not unearthed, and it needs to be stretched and grown to form stems and leaves around the beginning of February of the second year (the temperature is above 5) after the low temperature in winter, and blooms in March and April.

Flowers are a symbol of beauty, in this world, it is precisely because of the colorful flower embellishment that it has become colorful, and around us, the flowers we usually see are basically colorful, but only the black flowers are the least common, so why are there so few black flowers?

There are really black flowers in nature, which generally grow at higher altitudes, and there is a black tulip in Europe.

There are few black flowers in nature mainly for two reasons: one is that if the flower grows black, it means that it has to absorb the heat of all color light, and the delicate flower is easily burned; The second reason is that the light reflected by the black flowers is so small that the pollinating insects may not be visible at all, and they cannot attract insects to pollinate it, and it is difficult for the race to continue.

Have you ever observed that black flowers are extremely rare in nature? Therefore, dark flowers are often particularly precious, and black chrysanthemums and black peonies have become treasures among flowers. So why are black flowers so rare?

01 The reason why nature does not evolve black flowers is due to two considerations, the first is the safety of the flowers themselves. We all know that sunlight is composed of 7 different colors of light, the wavelength of these 7 kinds of light is different, and the heat carried by them is not the same, among which the heat of red light and yellow light is more, so most of the flowers in nature choose to reflect red light and yellow light, so as not to be burned, so the number of red flowers and yellow flowers is the largest. And if a flower grows black, it means that it has to absorb the heat of all colors of light, and the delicate flowers are easily burned, so there are few black flowers in nature.

02 Another consideration is the need for succession. Plants cannot move on their own, so pollination can only be done with the help of other forces in nature, for wind-borne flowers can be pollinated by wind, but insect-borne flowers need the cooperation of insects. So how to attract the attention of insects has become something that they have to consider in their evolution.

03 There are two types of insect eyes: monocular and compound eye, the monocular is responsible for simple light sensitization, while the compound eye is similar to the human eye and is responsible for imaging. However, the wavelength of light that insects can see with their eyes is different from that of humans, some insects can see ultraviolet light, while others cannot see all visible light. So if there is a black flower in the midst of a thousand flowers, it may seem abrupt to us humans, but it may not be visible at all in the eyes of insects, because the black flower reflects too little light.

04 For these two considerations, there are very few black flowers in nature, and scientifically researched that less than 10 of the more than 4,000 kinds of flowers in nature are black (strictly speaking, almost black), most of these flowers live in shady places and need to absorb heat as much as possible, otherwise they will freeze to death.

This is because chlorophyll is needed to form green, and chlorophyll is generally found in the stems and leaves of plants, and very little in the petals.

Because the chlorophyll content in the petals is very small, the cause of green is mainly related to chlorophyll, so this situation will occur.

Because most of the green plants are vines with some leaves and flowers, the pigment in the petal epidermis is rarely precipitated green.

Black flowers are very rare in nature, especially when real black flowers do not exist!

The main reason is that black absorbs all the light waves in the sunlight and is easy to absorb heat, just like we wear black clothes in the summer, getting hotter and hotter.

If the flowers are black, they will burn the delicate flowers, and without the plant's ability to protect itself, they will die quickly.

Secondly, the black color is too dark to be easily found by insects, which reduces the possibility of insect pollination, and without the help of insects, it will naturally not be passed on to the next generation, so it is easy to be eliminated.

The black flowers we see are actually crimson or deep purple flowers that are close to black, that is, what we call "red purple, purple black" in daily life, such as black peony, black tulip, black rose.

Flowers, colorful, very beautiful; It is appreciated by people, used as gifts, decorations, and to commemorate the deceased. Some articles are locked, so replace them with flowers, to commemorate a great man.

1. There are no pure black flowers in nature, but there are flowers that are close to black, such as black chrysanthemum and black peony, which are very close to black.

2. Black peony: The peony whose color is close to black is not really black as ink charcoal, among which the most slippery and famous ones are oolong lying ink pool, green dragon lying ink pool, crown world ink jade, smoke velvet purple, etc.

3. Ink chrysanthemum: Ink chrysanthemum is a precious flower and plant, also known as ink lotus, and is one of the top ten famous chrysanthemums in China. The flower color is dark purple, the branches are black and purple, the thickness is different, the initial flowering period is lotus type, the full flowering period is reverse roll type, the petals are thin, the color is black and red, shiny, and velvet, and there are circular and curved flowers in the center of the flower.

The flower disc is huge, the petals are hollow and the ends are curved, the flower diameter is like a palm, red with purple, purple and black; The core of the flower is thick, the orange is as thin as silk, and the color is like ink.
