Hello mate,

In this post, I am going to tell you the secret behind the question Why does the Sunflower always face the Sun? 

In our Childhood days, we will be very active in asking questions about the natural phenomena.

But we don't get the valid or reasonable answer to our questions.

So this is also one kind of the question that we would have asked in our childhood that Why does the Sunflower always face the Sun?

But some of us may not satisfied with the answer we got.

But, in this post I am posting the valid, reasonable and also the scientific reason for the question Why does the Sunflower always face the Sun? 

Sunflower seems to follow the Sun from morning to evening. All plants show a tendency to orient itself in response to light, which is called Phototropism. 

It is a growth hormone called Auxin that helps the Sunflower to exhibit phototropism. 

Auxin is sensitive to sunlight and moves away from it. So Auxin often migrates to the shaded part of the stem.

Once there, Auxin stimulates the growth of the cells. This causes the stem to become bulkier and lean in opposite direction i.e. towards the Sun.

As the direction shade changes, Auxin also shifts their position in the stem. This keeps the sunflower always facing the sun.

So that I hope that the secret of this natural phenomenon was useful to you.

Share this secret with your friends.
