Vedclass · Answer

(B) Photomorphogenesis is the light-mediated development of plants. The action spectrum for various photomorphogenic responses,such as seed germination and flowering,shows that plants are most sensitive to $Red$ light $(660 \ nm)$. The phytochrome pigment exists in two interconvertible forms: $Pr$ (which absorbs red light) and $Pfr$ (which absorbs far-red light). The conversion of $Pr$ to $Pfr$ by red light triggers these developmental processes.
