Sunflower petals close up primarily in response to changes in light and temperature. This phenomenon, known as nyctinasty, helps protect the flower during the night and may aid in conserving moisture. By closing, the petals can also shield the reproductive parts from potential damage caused by cold or rain. In the morning, the petals typically open again to attract pollinators.
