Photoperiodism is a physiological response of plants and animals to the duration of daylight and darkness. It involves the regulation of various biological processes based on the length of day and night. Photoperiodism plays a crucial role in the timing of flowering, reproduction, and other seasonal changes in plants. In animals, it influences behaviors such as migration, hibernation, and breeding. The perception of light by specialized photoreceptor cells triggers these responses, leading to the adaptation and survival of organisms in different environments.
