(B) The red-far red light response in plants is mediated by the pigment phytochrome. Phytochrome exists in two interconvertible forms: $Pr$ (red light absorbing) and $Pfr$ (far-red light absorbing). When $Pr$ absorbs red light,it converts to $Pfr$,which is the physiologically active form that triggers biological responses. When $Pfr$ absorbs far-red light,it converts back to $Pr$. The final physiological response of the plant depends on the last light exposure received,as it determines the final ratio of $Pr$ to $Pfr$ in the plant tissues. Therefore,the last treatment is the most effective in determining the plant's response.
