Why do sunflowers always follow the sun

It is related to two things in the sunflower body, auxin and lutein.

The main reason why sunflowers rotate towards the sun is the influence of light. Its auxin is distributed by the backlight, and the concentration of auxin on the side facing the sun is lower, and the concentration of auxin on the side of the backlight is higher, so the backlit side grows faster, and the light-oriented side grows slower, which makes the stem bend against the light, making it towards the sun.

Sunflowers have a substance called auxin, which can make plants grow tall and big, but they are timid and afraid of the sun, so the auxin in the neck of the sunflower will run to the side of the backlight to avoid it when it sees the sun, but the auxin on the backlit side is more and more, and they will cause this side to grow very fast, while the sunny side grows slower, so the plant bends to the side with light. As the sun moves in the sky, auxin is constantly moving against the sun's back, like "hide and seek". As a result, we often see sunflower discs that are always facing the sun, turning from east to west every day, and so on.

Because sunflowers need sunlight.

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, the sunflower will rotate with the sun, and when the sun goes down, the auxin it contains will be redistributed again, so it will turn back to its original position.

Its leaves and flower disks follow the sun from east to west during the day, although not instantaneously, and botanists have measured that the orientation of the flower disc is about 12 degrees behind the sun, or 48 minutes. After the sun goes down, the sunflower disc slowly swings back again, and at about 3 a.m., it faces east and waits for the sun to rise.

Answer: The main reason why sunflowers turn towards the sun is the influence of light. The auxin of the sunflower is distributed above the tip of the stem and is constantly transported downward, and it is affected by light. Some scientists believe that the flower tray of sunflowers is very sensitive to heat, and when the tubular florets are heated by the brazier, the fibers will shrink.

Why do sunflowers face the sun.

Aren't others too stupid, we were introduced to us by friends

Because the auxin in the receptacle of the sunflower is backlit, the stem on the backlit side grows faster, and the stem bends towards the light source.

Sunflowers are named because the top of the young plant in the early stage of growth and the young flower disc in the middle stage rotate very clearly with the sun. It is believed that sunflowers are only related to light exposure, but in fact, they are also closely related to gravity. 

The sunflower will rotate because it has auxin under the flower disc, which can promote the growth and development of the plant, and it will also receive the restriction of sunlight, and the stem of the sunflower will hold the flower disc and bend towards the side with the sun. When the sun goes down, the auxin it contains is redistributed, so the flower disc will turn back to its original position until 3 a.m., when it faces east and waits for the sun to rise.

The backlit side of the sunflower grows faster than the sunflower side, and the stem holds the sunflower's flower plate, bending in the direction of the sun, moving with the sun in the air.

I think maybe they need the sun so much that they turn around from morning to night, which brings a lot of energy to their lives.

Sunflowers themselves are very similar to the sun, and then they need to absorb sunlight every day.

Sunflower is a very sunny plant, it will always look for the direction of the sun and follow the sun.

It is determined by its own nature, and the substance it contains is very fond of sunlight and will rotate with the sun.

I think his name is called Sunflower because he always turns towards the sun.

Because the sun can make sunflowers produce flower seeds.

Hello, I'm glad to answer your question why sunflowers turn with the sun The reasons why sunflowers turn towards the sun are: 1. Sunflowers themselves are phototropic. 2. There is a special "plant biochemical" in the stem of the sunflower that moves with the sun.

3. The auxin of sunflower is distributed by backlight, and the backlit side grows faster and the light-oriented side grows slower. As a result, the stems of sunflowers are curved against the sun, all the way towards the sun.
