Vedclass · Answer

(D) The Emerson enhancement effect is the increase in the rate of photosynthesis when chloroplasts are exposed to light of two different wavelengths simultaneously,compared to the sum of the rates when exposed to each wavelength separately.Robert Emerson observed that the rate of photosynthesis drops significantly when plants are exposed to light with a wavelength greater than $680 \ nm$ (far-red light).However,when light of a shorter wavelength (less than $680 \ nm$) is provided along with the far-red light,the rate of photosynthesis increases dramatically.Therefore,the enhancement effect requires both wavelengths greater than $680 \ nm$ and wavelengths less than $680 \ nm$ to activate both Photosystem-$I$ and Photosystem-$II$ simultaneously.

The wavelength required for the Emerson enhancement effect is........
