  2. Photosynthetically active radiation - Wikipedia

    en.wikipedia.org/wiki/Photosynthetically_active...

    Radiation reaching a plant contains entropy as well as energy, and combining those two concepts the exergy can be determined. This sort of analysis is known as exergy analysis or second law analysis, and the exergy represents a measure of the useful work, i.e., the useful part of radiation which can be transformed into other forms of energy.

  3. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    Photosynthesis is the only process that allows the conversion of atmospheric carbon (CO2) to organic (solid) carbon, and this process plays an essential role in climate models. This lead researchers to study the sun-induced chlorophyll fluorescence (i.e., chlorophyll fluorescence that uses the Sun as illumination source; the glow of a plant) as ...

  4. Quantum biology - Wikipedia

    en.wikipedia.org/wiki/Quantum_biology

    Photosynthesis refers to the biological process that photosynthetic cells use to synthesize organic compounds from inorganic starting materials using sunlight. [58] What has been primarily implicated as exhibiting non-trivial quantum behaviors is the light reaction stage of photosynthesis.

  5. Hill reaction - Wikipedia

    en.wikipedia.org/wiki/Hill_reaction

    These are known as Hill reagents. These dyes permitted the finding of electron transport chains during photosynthesis. Dichlorophenolindophenol (DCPIP), an example of these dyes, is widely used by experimenters. DCPIP is a dark blue solution that becomes lighter as it is reduced. It provides experimenters with a simple visual test and easily ...

  6. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Schematic of photosynthesis in plants. The carbohydrates produced are stored in or used by the plant. Composite image showing the global distribution of photosynthesis, including both oceanic phytoplankton and terrestrial vegetation. Dark red and blue-green indicate regions of high photosynthetic activity in the ocean and on land, respectively.

  7. Biophysics - Wikipedia

    en.wikipedia.org/wiki/Biophysics

    Biophysics is an interdisciplinary science that applies approaches and methods traditionally used in physics to study biological phenomena. [1] [2] [3] Biophysics covers all scales of biological organization, from molecular to organismic and populations.

  9. Photochemistry - Wikipedia

    en.wikipedia.org/wiki/Photochemistry

    Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible (400–750 nm), or infrared radiation (750–2500 nm). [1] In nature, photochemistry is of immense importance as it is the basis of photosynthesis, vision, and the formation of vitamin D with sunlight. [2]
