What are sunflowers doing at night? Such a passage circulated on the Internet. It is said that the sunflowers follow the sun, so what happens to the sunflowers when they go down from the east and come out from the west? A shake of the head?
Think of you roaming in a sunflower bush, and when the sun is about to rise, hundreds of thousands of sunflowers shake their heads violently. I think from now on, you can't take care of yourself.
So how does the sunflower go back to the east, is it really a shook head? Aren't you looking down at the melon seeds?
In fact, the sunflower's sun is actually exaggerated with a certain deviation, not as general as the reference book, sunflowers often face the sun.
There are complex biochemical mechanisms behind any biological phenomenon. Biologically, the concentration of auxin controls the positivity of the aboveground part and the backlight of the underground part. This plant hormone is produced by vigorously dividing tissues and is also affected by light, allowing the plant's lightward and backlit sides to exhibit different growth rates on the backlit and backlit sides of the abs. Directional curvature occurs, and cells in different parts of the plant are less sensitive to auxin, and exceeding the optimal concentration of auxin inhibits growth.
Therefore, different parts of the plant are also bent in different directions under the light. Sunflower auxin has three characteristics, first of all, it can inhibit the growth of promoted cells, accelerate and slow down the division and reproduction of cells. The second is the backlight, when the light energy is illuminated, it runs to the backlight side.
This last point is called acute transport. That is, it is transported from the upper end of morphology to the lower end of morphology, and cannot be transported backwards. This is a period of time before the sunflowers germinate to the blooming of the flower disc. It is indeed the rising sun of the sun, emerald green. On the east side of the sunflower, the growth-thriving apical right mirror is more distributed on the west side of the backlight due to sunlight exposure. The cells on this side grow longitudinally and grow rapidly, with the result that the right neck is bent towards the slow-growing east side. That is to say, the flower disc at the top of the sunflower bends eastward in the morning. As the movement of the sun in the air changes, the direction of the sun, the sunflower disc also changes direction, but it is not timely to follow the change.
Botanicals have measured it. And the pointing of the flower disc is about twelve degrees behind the sun, that is, forty-eight minutes, standing upright at noon, and bending west in the afternoon. These all manifest as curved masculines of the attraction. After the sun goes down, the sunflower flower plate slowly swings back. At about three o'clock in the morning, it faces the east and waits for the sun to rise, but once the flower disc is in full bloom, it no longer rotates toward the sun, but is fixed towards the east.
To say sunflower, do you know its flower language? The flower language of the sunflower is: loyal and firm, silently guarding love, and the meaning of the sunflower is: love for life. Sunflower is a bright but persistent flower, it can represent love, but also symbolize people's pursuit of a better life.
With the help of this sunflower that sniffs melon seeds, get out the person you want to protect.
