Answer Posted / mahalakshmi
Facing of pancy towards the sun is known as phototropic
movement. This is due to presence of auxin, a growth harmone
in the stem.
When the stem tip receives unilateral light, the
concentration of auxin increases in the shaded side.
The higher concentration of auxin in the shaded side causes
that side to grow faster, resulting in a positive
phototropic curvature.
