The pigment absorbs most of the wavelength present within the blue-violet and orange-red part of the light, and reflects the yellow-green light, resulting in the appearance of green color of such parts. It is found in most of the photosynthetic organisms belonging to eukaryotes, cyanobacteria, ...
Chlorophyll A is a form of chlorophyll that absorbs light in the violet to red spectrum (approximately 400-700 nm wavelength range) and reflects green light (500-570 nm wavelength), which imparts the characteristic green color to land plants. It is occurs in all photosynthetic organisms and is...

Photosynthetic antenna proteins can be thought of as “programmed solvents”, which bind pigments at specific mutual orientations, thus tuning the overall energetic landscape and ensuring highly efficient light-harvesting. While positioning of chlorophyl
(SZA) to represent clear-sky PAR. This approach may lead to overestimations of GPP and photosynthesis under actual weather conditions88. Thus, additional cloud removal algorithms may be required to accurately characterize SIF in complex weather conditions. The HCSIF dataset effectively reflects ...
The spectrophotometric method uses the wavelengths related to spectral absorption peaks of chlorophyll in the red region of 645–663 nm (Song et al., 2020), while the SPAD value reflects the absorption intensity in the red (650 nm) and near-infrared (940 nm) region (Chang and Chang, 2014...
Plots are formed using data collected at a high sampling rate within a second of the dark-adapted leaf being exposed to light, as the independent variable on a logarithmic timeline. On such plots, inflection points (J-I-P) are noticed when the recorded fluorescence increases which provide the...
Clearly, this reflects the fact that cyanobacteria are photoautotrophs that harvest light for photosynthesis at a number of differ- ent wavelengths, the amounts of which are dependent on the level they inhabit in a water column and competition from other photosynthetic organisms14. Recent research...
The color of the solution disappeared after two hours radiation while the pH decreases from 6.38 for un-radiated to radiated celery solution 4.17 after 24 hours with liberation of carbon dioxide which indicates destroying of chlorophyll but the absorption at 400-210 nm still exists which reflects ...
Plants and other photosynthetic organisms use chlorophyll to absorb light (usually solar energy) and convert it into chemical energy. Chlorophyll strongly absorbs blue light and also some red light. It poorly absorbs green (reflects it), which is why chlorophyll-rich leaves and algaeappear green. ...
