Vedclass · Answer

(D) Phytochrome exists in two interconvertible forms: $Pr$ (inactive form,absorbs red light) and $Pfr$ (active form,absorbs far-red light).When a plant is exposed to continuous red light,the $Pr$ form is converted into the $Pfr$ form.However,the $Pfr$ form is unstable and undergoes degradation or reversion back to $Pr$.In a state of continuous red light,the plant maintains a dynamic equilibrium where the rate of synthesis of $Pr$ and the rate of degradation/conversion of $Pfr$ reach a steady state,ensuring the plant can continue to respond to light stimuli.
