Photoperiodism
Photoperiodism is the biological response of organisms to the length of day and night. It plays a crucial role in regulating various processes, such as flowering in plants and breeding in animals. Different species can be classified as short-day, long-day, or day-neutral based on their sensitivity to light duration.
In plants, photoperiodism helps determine the timing of flowering and seed production. For example, soybeans are short-day plants that flower when nights are longer, while sunflowers are long-day plants that bloom with longer daylight. This adaptation allows organisms to synchronize their life cycles with seasonal changes.
