Explanation:
Detailed explanation-1: -Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light.
Detailed explanation-2: -Take a potted plant with variegated leaves like croton and keep it in a dark region, away from sunlight for 3 days. This will halt photosynthesis and de-starch the plant. Then keep the plant facing the sunlight for 6 to 8 hours. The plant can now carry out photosynthesis and produce starch.
