Final answer:
The statement that does not describe photoperiodism is the one about flowering being induced by temperature changes (d). Photoperiodism relates to the response to changes in the day length, affecting flowering and other growth processes in plants.
Explanation:
The statement that does not characterize photoperiodism is d) Induction of flowering in response to changes in temperature. Photoperiodism in plants is a biological response to the timing and duration of day and night rather than temperature changes. It primarily controls processes such as flowering, setting of winter buds, and vegetative growth.
Plants detect seasonal changes through a system that includes pigments like phytochrome and cryptochrome. These pigments help sense changes in the photoperiod, which in turn influences gene expression and the conversion of shoot apex into a flowering apex. This detection and response ensure the survival of the plant by synchronizing flowering with the appropriate season for pollination and seed setting.
