Looking down from a height, the sunflower flowers are boundless, like a golden ocean. The soft light emitted by the sun quietly gilds the sunflowers with a layer of gold foil, making them radiant and energetic, just like graceful girls, very beautiful.
As I walked along the path composed of sunflowers, I suddenly noticed a phenomenon; Why do sunflowers rotate with the sun? Why does it like to dance with the sunshine?
When I returned home, I quickly checked the book "100000 Why" and it was said that under sunlight, the content of auxin on the backlight side of sunflowers increased, stimulating the cells on the backlight side to elongate and cause the sun to rotate. After sunset, auxin is redistributed, turning the sunflower to the east. The role of auxin is to speed up reproduction, but it is afraid of sunlight. Its molecular structure has opticity. When the plane polarized light plane passes through the solution of chiral compounds, the direction of the plane polarized light plane is rotated to change an angle. The ability to rotate the polarization plane is called optical rotation. Chiral compounds have optical activity. Therefore, whenever the sun hits it, this optical activity causes the sunflower disc to rotate.
I see! "If I have any insights, so in the future, if you have anything you don't understand, I can serve as a commentator for you!
In summer, sunflowers bloom and bud! Its stamens are like silver needles, a bit prickly to the touch. The orange petals trembled under the gentle breeze, making them extremely beautiful.
In autumn, the "food" in the sunflower disc will mature, which is our favorite Sunflower seed. This is one of the reasons why I like sunflowers. The pericarp of Sunflower seed is lignified, grayish black, obovate, slightly compressed.
However, in winter, the sunflowers wither and the seeds fall on the ground. So, in the cycle of spring, summer, autumn, and winter, sunflowers grow repeatedly and repeatedly.
Sunflowers smell with a faint floral aroma and melon seed flavor. When it is still, it looks like a resolute warrior, standing straight and looking ahead. When it moves, it will turn towards the sun, and the petals and leaves will also tremble slightly, so it can help us identify the direction in summer. Sunflowers have many uses, and their fruits can be eaten raw or fried as snacks, making them a seasonal snack. Moreover, fruits can also be used to extract oil and become food oil for cooking delicious meals.
I like the strong and sunny sunflowers of warriors.
On Saturday morning, I was playing alone at my doorstep. There is a cluster of sunflowers at the door. The stems and leaves of the sunflowers are particularly beautiful and green, while the outside is golden, like the golden color of the sun's outer circle drawn by children. Although it is also golden inside, it has a hint of red and is darker than the golden outside. The red color is also darker.
When the flower core grows in a sunflower during its mature season, the flowers will turn into delicious Ao. Sunflowers follow the sun every day. It's like being a follower of the sun. When the sun rises from the east, the sunflowers turn eastward, which is extremely interesting. But why do sunflowers follow the sun? I couldn't figure it out and went to find my dad.
Dad said solemnly, "There is a substance called plant main growth agent in the area under the sunflower plate, which has the function of accelerating reproduction but has the ability to dislike rotation. Every time the sun rises, the stem of the sunflower will immediately hide on the backlight side, making it appear that the entire plant is bending towards the unfamiliar area
After listening to my father's words, I realized that the reason why sunflowers walk towards the sun is really interesting. I discovered this little-known secret, the magical sunflower.
As soon as summer arrives, in this growing season, sunflowers have bid farewell to their youth and begun to grow continuously. A flower bud grew from the top of the sunflower's head, which was its small green flower plate. The flower tray grew day by day and finally bloomed like a wheel. Many golden petals surround the flower tray, as if wearing a hat. In the middle of the flower plate is the densely packed stamens, one by one. You should know, it may grow into very delicious melon seeds in the future!
In the morning, sunflowers always bloom with their most beautiful smiles, being the first to greet the rising sun from the east; At noon, in the scorching sun, sunflowers always look up their golden faces and chat with the white clouds, breeze, and sun! Look at how happy it is playing, it's like a mischievous child, always smiling and occasionally shaking his head, curious about everything around him; In the evening, the sun slowly sets, and the sunflower swings towards the west, swinging its leaves like the sun's father-in-law bidding farewell. Look at it, how much it looks like a little sun!
The loveliness of sunflowers lies not only in their appearance, but also in their spirit - continuous dedication!
When sunflowers mature, the flower plate will be picked by others, because in that small flower plate, there is a huge treasure - melon seeds, which are a highly nutritious food!
Although the life of a sunflower is very short, it is willing to dedicate everything to humanity!
Seeing sunflowers, I feel as if I have seen the sun, joy and freedom.
Ah! What beautiful sunflowers! It seems like an invisible sunlight has shone into my heart!
Sunflowers grow in the sun regardless of the seasons. In addition to their appearance resembling the sun, they also have bright and generous flowers, and their entire body is full of treasures.
If you plant sunflowers all over the hillside, in autumn and summer, when you see these sunflowers turn into a golden ocean, the sunflowers in that golden ocean will all face in one direction - east. Don't you think it's spectacular when you see this scene? Is it very pleasing to the eye?
And I heard from my grandfather that sunflowers are all medicine, including seeds, flower discs, stems and leaves, stem pith, roots, flowers, etc. It can calm the liver and dispel wind, clear dampness and heat, eliminate stagnant qi, and has extremely high medicinal value.
The sunflower seeds can also be fried into oil for people to eat, and the melon seeds grown on the sunflower tray must have been eaten by everyone, giving it a light and refreshing taste.
Since sunflowers have so many functions, why not plant some sunflowers at home? Is the selfless spirit of sunflowers worth learning from? There is a poem that describes sunflowers as follows: "No willow catkins rise from the wind, only sunflowers tilt towards the sun. I appreciate the sunflower's pursuit of brightness and the spirit of making progress every day, and I also want to learn from it to enrich my dedication to society.
Although its colors are not as dazzling as roses or as delicate as daffodils, its spirit of yearning for light every day washes people's hearts. No matter how much wind and rain it experiences, as long as there is sunshine, it immediately holds its head high.
