How do plant hormones influence a plant's response to light?

Plant hormones, particularly auxins, influence a plant's response to light through a process called phototropism. Auxins are distributed unevenly in the plant, causing cells on the side of the plant that is away from the light to elongate more, resulting in the plant bending towards the light source.

This answer effectively explains the mechanism of phototropism and the role of auxins in this process. The question assesses the student's ability to apply their knowledge of plant hormones to a specific growth response, demonstrating understanding of how plants adapt to their environment.
