Sunflower Fact: Everyone has heard the name of sunflower flower, as well as probably everyone must have heard the things said about it, as it remains more active in summer than in winter. The direction of this flower also keeps on changing throughout the day. It flourishes well in those areas where there is sunlight for more than 6 hours. It is said that even if there is a severe drought, even then it does not matter to the sunflower. In the end, the most important thing that is said about this is that the direction of the sunflower flower is where the sun is. In fact, these things are not in vain, but there is a scientific basis for all these things.
understand flower activity
To know the activity of sunflower, you have to look at this flower. First of all you see it before sunrise. You will find that all the flowers are facing east. They have not fully bloomed yet, but are in the process of blooming. When the sun rises, you will find that the bunch of new and fresh flowers are in the direction of the sun and are enjoying the sun rays very comfortably.
change direction of flowers
There are also some old flowers in this bunch. You will see new flowers blooming towards the east, while some old flowers will be seen almost withered towards the west. The blooming of these flowers towards the east or following the movement of the sun is a special scientific method which is called heliotropism in science. Sunflower flower moves according to the direction of the sun. But, in the night they change their direction towards the east and wait for the sunrise.
What is heliotropism?
A study on heliotropism in the year 2016 said that just as humans have a ‘biological clock’ or biological clock, similarly sunflower flowers also have such a clock that detects sunlight and in Motivates the flowers to turn that way. This biological clock affects the genes of these flowers. Research has been told about the 24-hour ‘circadian rhythm’. Sunflower flowers also rest at night like humans and remain active during the day. With the increase of rays, the activity of flowers also increases.

this is the real reason
The stems of new sunflower plants grow more at night. The special thing is that this development in the stem takes place only towards the west. That’s why they automatically bend towards the east. As the day progresses, the direction of growth of the stem also changes. The stem grows towards the east and the flowers on it start bending towards the west. This cycle goes on like this continuously.
