Answers
GPT-4o mini
Positive phototropism is the growth response of a plant to light, where the plant bends or grows toward the light source. This phenomenon is primarily observed in stems and leaves, allowing plants to optimize their exposure to sunlight, which is essential for photosynthesis.
The process is driven by the hormone auxin, which regulates plant growth. When light shines on one side of a plant, auxin accumulates on the shaded side, promoting cell elongation on that side. As a result, the plant bends toward the light to maximize its ability to capture light energy for growth and development. This adaptive response helps ensure that the plant can thrive in its environment.
