Detailed explanation-1: -The photosynthetic experiment of the Emerson effect takes place on Chlorella. The red drop effect observes on monochromatic light. The Emerson Enhancement effect observes on synchronized light of 680 nm and 700 nm. Both processes take place in the photosynthesis of plants.
Detailed explanation-2: –Red drop effect is seen in the red part of the spectrum and leads to a drop in efficiency of photosynthesis, leading to the given name.-The Emerson effect is the increase in the rate of photosynthesis after chloroplasts are exposed to light of wavelength 670 nm (red light) and 700 nm (far red light).
Detailed explanation-3: -The red drop experiment was demonstrated by Robert Emerson and Charlton Lewis in 1943. The scientists set an experiment for oxygen evolution in the green algae Chlorella pyrenoidosa and examined the action spectrum in the visible region.
Detailed explanation-4: -Two wavelengths together increase the quantum yield of photosynthesis. The Emerson enhancement effect refers to the increase in quantum yield of photosynthesis when monochromatic beams of two different wavelengths (680 and 700 nm) are used together on the test organism (Chlorella).
