The sunflower flower is known for its beauty and unique properties. It is one of the largest flowers. The beauty of this flower increases in sunlight. The special thing about this flower is that it always faces the direction of the sun. That is, the sunflower flower also rotates in the same direction from which the rays of the sun come. This scene is very captivating. It is clear from the name of the sunflower flower that it is a flower facing the sun. The thing to note is that this does not happen with all flowers, it happens only with sunflowers. But have you ever wondered what is there in the sunflower that its face keeps rotating with the rays of the sun? Actually, there is a scientific reason behind this. Let us know about this in detail in this article.
The reason sunflower flowers turn in the direction of the sun is due to a process called heliotropism. Heliotropism is a process in which plants grow in the direction of sunlight. Heliotropism is especially seen in young sunflower flowers. These flowers turn east as the sun rises in the east and move west with the movement of the sun during the day. At night, they slowly return to the east, so that they are ready for sunrise the next day.
Heliotropism is caused by a hormone called auxin. Auxin aids in plant growth. When sunlight hits a sunflower stem from one side, auxin accumulates in the shadowed side of the stem. The high concentration of auxin causes the shadowed side of the stem to grow faster, causing the flower to turn toward the sun.
The sunflower flower also has an internal biological clock that plays a role in heliotropism. The biological clock is also called the biological clock. This clock helps the flower to know what time of day it is and what direction the sun is in. The biological clock also helps the flower to return to the east at night and be ready for sunrise the next day.
Sunflowers are not only beautiful, but they also have many benefits. They are an important source of oil, seeds, and biofuel. Sunflower flowers attract pollinators, which help other plants reproduce. In addition, sunflower plants also help remove toxins from the soil.
