2. Photosynthetically active radiation - Wikipedia

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

   However, photosynthesis is a quantum process and the chemical reactions of photosynthesis are more dependent on the number of photons than the energy contained in the photons. Therefore, plant biologists often quantify PAR using the number of photons in the 400-700 nm range received by a surface for a specified amount of time, or the ...

3. PI curve - Wikipedia

   en.wikipedia.org/wiki/PI_Curve

   The PI (or photosynthesis-irradiance) curve is a graphical representation of the empirical relationship between solar irradiance and photosynthesis. A derivation of the Michaelis–Menten curve, it shows the generally positive correlation between light intensity and photosynthetic rate.

4. 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 ...

5. Endergonic reaction - Wikipedia

   en.wikipedia.org/wiki/Endergonic_reaction

   All physical and chemical systems in the universe follow the second law of thermodynamics and proceed in a downhill, i.e., exergonic, direction.Thus, left to itself, any physical or chemical system will proceed, according to the second law of thermodynamics, in a direction that tends to lower the free energy of the system, and thus to expend energy in the form of work.

6. Plant stress measurement - Wikipedia

   en.wikipedia.org/wiki/Plant_stress_measurement

   The most commonly used protocols include those aimed at measuring the photosynthetic efficiency of photosystem II, both in the light (ΔF/Fm') and in a dark-adapted state (Fv/Fm). Chlorophyll fluorometers are, for the most part, less expensive tools than photosynthesis systems, they also have a faster measurement time and tend to be more portable.

   With President-elect Donald Trump's recent announcement of former surgeon-turned-TV host Dr. Mehmet Oz to lead the Centers for Medicare and Medicaid Services (CMS), questions are swirling about ...

9. 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.
