What color are these flowers?

Question 1: What color are the flowers? Colorful flowers

The blooming flowers are colorful and dazzling. Some are red as blood, some are white as jade, some are yellow as orange, and some are black as ink. So gorgeous

How is the fragrant color formed? It turns out that the color of petals is determined by the pigments contained in petal cells. These pigments can be classified into three categories.

The first is carotene, which exists in the chromophore or chloroplast of cells. There are many kinds, not only petals, but also roots, leaves and fruits.

There are also. Petals appear red, orange and yellow, which is caused by this pigment.

The second is anthocyanin, which mostly exists in plant cell fluids in the form of glycosides (anthocyanins) formed by the combination of sugars such as glucose. Because anthocyanins are about

There are 20 species, including anthocyanin 130. The petals of various plants contain different amounts and kinds of anthocyanins, so the range of flower color development is large. When the cell sap is acidic

During sex, it can be red, pink, orange, etc. Purple when neutral; When the cell sap is alkaline, it is blue.

The third category is flavonoids, which also exist in petal cell fluid in the form of glycosides, and can present various colors from light yellow to deep yellow. The more alkaline the cell fluid is,

The deeper its yellow becomes, on the contrary, if the acidity is stronger, the lighter its yellow becomes.

Yellow flowers are common. Flavonoids are the most common pigments in pale yellow petals, such as buttery and ivory flowers such as snapdragon and dahlia.

Yes Dark yellow, such as tulip, lily and wild rose, is mainly formed by carotenoids. There are also some flowers, such as marigold and sorrel.

Its deep yellow color is the result of the synergistic color development of carotenoids and flavonoids. It is generally believed that carotenoids have a more significant yellow effect than flavonoids.

Neroli is related to the ratio of carotenoids and anthocyanins. If the former content is more, it is yellow-orange, like orange lily;

But when the latter content is more, it is red and orange, like the orange petals unique to geranium; The change of the two contents shows the subtle difference of color influence.

It's different.

Red and pink flowers, such as peony and peach blossom, are related to anthocyanins. The depth of red petals is determined by anthocyanin content.

Yes

There are many blue flowers in nature, which are very delicate and charming, such as carnations and cornflowers. But scientists have never found blue pigment in flowers.

Anthocyanin is the main pigment extracted from blue petals such as cornflower and carnation. So how does anthocyanin appear blue? This question,

After decades of debate, no conclusion has been reached. However, some scientists believe that this is because the combination of anthocyanins, metal elements and accessory pigments has become a very complicated one.

Complex, blue appears in the cell sap of flowers, so there are blue flowers, such as the anthocyanins in the blue petals of Dianthus caryophyllus, which are composed of metal atoms such as potassium and sodium.

Synthetic salts exist and are very stable, and will not change color due to the change of pH value of cell fluid. Green flowers and blue and white flowers mean that chlorophyll is the main pigment in flowers.

As for the white flower, which accounts for 30% of the color, it contains no pigment, but the tissue is covered with countless small bubbles, so it looks white. If we squeeze this out,

Some bubbles, white flowers will become colorless. In fact, some scientists believe that there are no pure white flowers in nature, and the pigments in white petals exist.

Very shallow flavanone found in petals.

So, how many colors are there among thousands of colors? Someone counted more than 4000 colors and found that there were white, yellow, red, blue, purple, green,

9 colors such as orange, brown and black. Among them, white is the most, followed by yellow flower, safflower, blue flower, purple flower, green flower, orange flower and camellia, and the least is black flower.

The color of flowers mostly changes between red, blue and purple, followed by yellow, orange and orange-red.

Colorful gives people beautiful enjoyment, but for the plant itself, it is only a sign of attracting insects to pollinate. Different colors are different.

Favored by insects: bees like blue and yellow, and also like white with flavonoids; Beetles generally have a poor sense of color and tend to be dull.

Cream or green flowers; Butterflies like bright colors such as red and purple; Moths like red, purple, lavender and white; Flies like dull colors and brown, purple or red.

Green; Hornets like brown. ...& gt& gt

Question 4: What color is the winter jasmine? According to the surface morphology of epidermis and the arrangement relationship between guard cells and adjacent cells, stomata can be divided into four types: irregular, unequal, parallel and horizontal. The irregular type is also called Ranunculaceae type, and the cells adjacent to the guard cells have the same morphology as other epidermal cells and surround the guard cells irregularly. The stomata of buttercup and watermelon belong to this type. Unequal type, also known as Cruciferae type, is surrounded by three layers of secondary guard cells with different sizes, which are different in size and shape from other epidermal cells. This type of stomata usually exists in plants of Cruciferae (such as Brassica) and Sedum (Sedum). The parallel type, also known as Rubiaceae type, is accompanied by one or several subsidiary guard cells on the side of each guard cell, and the long axes of the guard cells and the subsidiary guard cells are parallel to the long axes of stomata. This type of stomata is common in Rubiaceae (such as Rubiaceae) and Papilionaceae (such as kidney bean). The horizontal type is also called Dianthus type, and each stomata is surrounded by two subsidiary guard cells, and the cell walls of the subsidiary guard cells are at right angles to the long axis of the stomata. This type of stomata is common in Dianthus (such as Dianthus) and Acanthaceae (Acanthaceae).

Question 5: What color flowers? (At least ten species) White oleander red oleander purple February orchid pink Japanese cherry yellow wintersweet white daffodil pink rose green hydrangea red hibiscus red pomegranate yellow towel gourd flower

Question 6: What are the varieties and colors of wild flowers?

Question 7: What color flowers does Ginseng have? Pictures of red flowers.

Question 8: What is the brightest flower? According to some data, white flowers are the most common in nature, followed by yellow, red, blue, purple, green, orange and brown flowers. Black flowers are the rarest, which is the result of natural selection in the process of biological evolution. Because white and red flowers stand out against the green leaves and are easily recognized by pollinators, bees are most sensitive to white and yellow, and butterflies are good at distinguishing red, so white, yellow and red become more in natural selection. The reason why black flowers are rare is that black can absorb light waves and is easily damaged by them, so it is gradually eliminated by nature.

Question 9: What color are azaleas? At present, the common azaleas are Rhododendron and Rhododendron, and the color of Rhododendron is generally red. But there are many colors of rhododendron, such as light red, iron red and white, and these colors alternate with each other. But generally speaking, the traditional azaleas should be red. The legendary "cuckoo weeping for blood" means that the color of azaleas is stained with the blood of cuckoo birds. But I haven't seen the blood of cuckoo, and I don't know if it is red.

Question 10: What colors are the flowers in summer? Summer flowers are:
