Hey friend, Harish here.
Here is your answer.
The image posted in the question shows the plant growth movement towards the sun. It is something similar to the AVENA COLEOPTILL CURVATURE TEST.
☆ This was performed and observed by F.W Went and which lead to the discovery of a plant hormone called Auxin.
☆ The upper part of the sheet of a seedling has the Coleoptill. And it contained a chemical substance called Auxin.
☆ This Auxin when exposed to sunlight, moves to one particular side and making it heavier which in turn makes the plant bend towards the sun.
