Red drop photosynthese
WebThere are two evidences in favour of two pigment system in photosynthesis (a) Red Drop Robert Emerson: determining the quantum yield of photosynthesis in Chlorella by using monochromatic light of different wavelengths and observed a sharp decrease in quantum yield at wavelengths greater than 680 mu. WebDec 24, 2013 · Red drop effect is a phenomenon observed in case of photosynthesis in plants. It is observed a huge drop in the rate of photosynthesis at wavelength 700 nm. This is known as the "red drop" effect. The wavelengths of light beyond 700 nm are apparently of insufficient energy to drive any part of photosynthesis. This was observed by Emerson.
