Vedclass · Answer

(A) $P_r$ is the inactive form of phytochrome,which is blue in color.It specifically absorbs red light in the range of $660\ nm$ to $680\ nm$.Upon absorption of red light,it is converted into the active $P_{fr}$ form.The $P_{fr}$ form absorbs far-red light at approximately $730\ nm$ and converts back to the $P_r$ form.Therefore,the correct wavelength absorbed by the $P_r$ form is $680\ nm$.

The wavelength of light absorbed by the $P_r$ form of phytochrome is (in $nm$)
