Explanation:
Phototropism is the directional growth of a plant organ in response to light, typically positive in shoots. Geotropism (gravitropism) is the growth response to gravity, with roots showing positive geotropism (growing down) and shoots negative geotropism (growing up). Thigmotropism is the growth response to touch or physical contact, seen in climbing plants like vines, not water (which is hydrotropism). Thus, statements 1 and 2 are correct.
