Red drop phenomenon
Webesting expansion of the phenomenon which is becom-ing knozwn as the Emerson effect*. In particular, it shows that the so-called chromatic transient, as ob- ... do with the red drop, one could expect the quantum yield in this spectral region to improve with increas-ing temperature. The first experiments of Emerson WebThe red drop effect is a sharp decrease in quantum yield (number of oxygen molecules released per quantum of light absorbed- this number is usually 1/8 or 12%) at wavelengths greater than 680 nm in green plants. It is called the ‘red drop’ because it occurs in the red part of the spectrum. So the correct option is 'PS II'. Was this answer helpful?

WebWhen the available wavelength is beyond 680nm, the efficiency of photosynthesis decreases because PS1 stops performing. This effect is called the red drop effect. In other words, … WebMay 22, 2024 · Reason : In red drop phenomenon the rate of photosynthesis decreases. Answer Answer: (b) Although the efficiency of photosynthesis is uniform over most of the …
WebThe phenomenon of red drop shown by Emerson and Lewis was quite puzzling. This is not due to decrease in light absorption because the quantum yield measures only light that has actually S been absorbed. This oMy indicates that light of £ f. wavelengths greater than … WebJul 15, 2005 · 1. Introduction. The quantum yield of photosynthesis, calculated per absorbed light quanta, drops at the red end of the absorption spectrum of leaves and green algae [1], [2].This drop can be compensated with the help of an accompanying illumination at shorter wavelengths, a phenomenon known as Emerson enhancement effect [3].The reason of …

Here is a list of 50 craziest natural phenomenons around the globe that will surely … Webred drop The sharp decline in photosynthetic efficiency as the wavelength of exciting light enters the red region (above 680nm) due to the insensitivity of photosystem II to …
WebWavelengths beyond 700 nm are apparently of insufficient energy to drive any part of photosynthesis. So a huge drop in efficiency has been noticed at 700 nm. This phenomenon is called as red drop effect. In other words, there is a sharp decrease in quantum yield at wavelengths greater than 680 nm. So, the correct answer is option C.
WebThis phenomenon is called as RED DROP EFFECT. In other words, there is a sharp decrease in quantum yield at wavelengths greater than 680nm. d. Photorespiration: a respiratory process in many higher plants by which they take up oxygen in the light and give out some carbon dioxide, contrary to the general pattern of photosynthesis. ... for those with ears let them hearWebEmerson Red Drop and Enhancement Effect •The rate of photosynthesis is measured as the number of O2 molecules produced per quantum of light absorbed • Robert Emerson et al … dimension of heatWebWavelengths beyond 700nm are apparently of insufficient energy to drive any part of photosynthesis.
