It diffuses towards the shady side when light is coming from one side
D
It inhibits growth
Correct Option:
D
Explanation
Auxin is produced mainly in actively growing shoot regions, including the shoot tip, and promotes cell elongation. Under one-sided illumination it becomes more concentrated on the shaded side of a shoot, causing greater elongation there and bending the shoot toward light. Therefore the general statement that auxin "inhibits growth" is false in this context.
