Photoperiodism depends on which of the following factors?

Question

Quizplus · Accepted Answer

Photoperiodism, the physiological response of organisms to changes in day length, depends on the activation of photoreceptors, such as phytochrome, cryptochrome, and phototropins. These photoreceptors sense the duration and quality of light and transmit this information to regulate various developmental and physiological processes in plants and animals. Therefore, choice A is the best option. Daily fluctuations of auxin and the accumulation and stabilization of auxin are mainly involved in plant growth and development, while the inhibition of phytochrome can influence photomorphogenesis but not necessarily photoperiodism.
