Matter of Knowledge : After all, why does the face of the sunflower flower face the sun? this is the reason behind it
This question must have arisen within many of us at some point or the other that why are the sunflower flowers facing towards the sun? What is the reason behind this? In this episode, today we will know that why do sunflower flowers move in the direction of the sun? Let us tell you that the sunflower flower is more active in summer than in winter. The growth of these flowers is more in those areas, where sunlight comes out for more than 6 hours. Sunflower flowers develop very rapidly in hot and hot summers. In the morning, when the sun rises from the east, then the direction of the mouth of this flower is also in the east. Gradually, along with the direction of the Sun, their direction also keeps changing. The new flowers of the sunflower face more in the direction of the sun than the old flowers.
Our question was, why do sunflower flowers move only in the direction of the sun? In answer to this question, scientists say that this is due to heliotropism. Under this process, sunflower flowers are facing towards the sun. Along with the direction of the sun, the direction of their flowers becomes in the west in the evening.
However, at night, they change their direction again to the east and wait for the sun to rise the next day. This process goes on regularly. Now the question arises that what would have been heliotropism? Due to which the sunflower flowers move towards the direction of the sun.
In research conducted in the year 2016, it was found that just as there is a biological clock inside humans. In the same way, sunflower flowers also have a special type of arrangement, which is known as heliotropism. It is also called the biological clock of the sunflower. It detects the sun's rays and induces the flower to bend towards the side where the sun is.
It was also found in this research that these flowers rest at night and become active as soon as they get sunlight during the day. As the sunlight increases, so does the activity of sunflower flowers. Heliotropism is the process by which the face of the sunflower flower is in the direction of the sun.
