Plants are classified as long day, short day, or day-neutral based on how they respond to photoperiods, with phytochromes acting as photoreceptors that switch between Pr and Pfr forms under red and far-red light to control flowering. In long day plants, red light (Pfr form) promotes flowering, while in short day plants, it inhibits flowering—demonstrating the photo-reversible role of light in plant development.\n
