\nThe plant hormone responsible for phototropism is auxin. When a plant is exposed to sunlight, auxin distribution within the plant is altered. More auxin accumulates on the shaded side of the plant, causing cells to elongate and grow more rapidly on that side. This differential growth leads to bending towards the light source, allowing the plant to optimise its exposure to light for photosynthesis.
