The rate of photosynthesis when red and far-red light are given together is greater than the sum of the rates when they are given apart, the effect provided essential

evidence in favor of the concept that photosynthesis is carried out by two photochemical systems working in tandem but with slightly different wavelength optima

this effect is known as
