Why do sunflowers always face the sun? Is it really because you like sunshine?

Sunflowers always face the sun, but in fact they don't really like the sun, but there is an auxin in their bodies. As soon as the sun appears, this auxin will transfer to the backlight surface, which will promote the growth and division of cells on the backlight surface, while the sunlight surface does not contain this auxin, so it will grow slowly, which makes the sunflower appear phototropically curved, and its disk will always move towards the sun, and the sun will also move.

I think everyone has seen sunflower. It is a very beautiful flower. I remember when I was a child, there was a sunflower in my grandmother's yard. It is warm orange, which makes people feel very comfortable. In addition, sunflowers can produce sunflower seeds and eat them when they are ripe. This feeling is great. When I was a child, I discovered this magical phenomenon, that is, sunflowers will follow the sun, and sunflowers are low at night.

At that time, I thought it must be because sunflowers like sunshine very much, but it was not until I grew up that I found out that this was not the case. The reason for this phenomenon is that auxin is at work, which is called turning to the sun. Phototropism and turning your back on the sun? Backlight? In fact, many plants are like this, but there is no big disk like sunflower, so we can't see it clearly.

If there are flowers at home, it is suggested that you can observe your own flowers. Their leaves will always grow towards the sun. Because their placement position remains the same, they will show an inclined state. Is this a plant? Phototropism and some flowers have curly leaves. What kind of plants are they? Backlight? Actually, it's all caused by auxin.
