    Auxin is backlit at the receptacle, so the stem on the backlit side grows faster, and the stem bends towards the light source.

    Because the sunflower usually faces the east, after the sun sets, it slowly turns to the east, and the side with the sun on its back, because of the more auxin, grows faster and quietly covers the plum, and the sunflower is not rotating from small to large, and generally turns sullenly with the sun during the period from germination to flowering.

    This is because the side with his back to the sunflower has more auxin, and the chlorophyll socks tremble more, and it grows faster, so it will control the sunflower and face the sun.

    It is related to the auxin in the sunflower. There is more ghrein on the side with the sun on its back, and it grows faster, so it grows towards the sun.

    It is because plants have a particularly strong phototropism, and if they grow towards the sun, they can obtain a particularly high level of nutrients, and the growth will become better and better.

    Sunflowers rotate with the sun because of the auxin underneath the flower disc, which promotes the growth and reproduction of the plant. There is also the restriction of sunlight, and the stem will drag its flower disc and bend towards the side with the sun. When there is sunlight, sunflowers will rotate with the sun.
