  3. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen , cellulose and starches .

  4. Plant stress measurement - Wikipedia

    en.wikipedia.org/wiki/Plant_stress_measurement

    [12] [13] It is a light adapted test that allows one to measure plant stress while the plant is undergoing the photosynthetic process at steady-state photosynthesis lighting conditions. Like FvFm, Y(II) represents a measurement ratio of plant efficiency, but in this case, it is an indication of the amount of energy used in photochemistry by ...

  5. Soil fertility - Wikipedia

    en.wikipedia.org/wiki/Soil_fertility

    Photosynthesis is the process whereby plants use light energy to drive chemical reactions which convert CO 2 into sugars. As such, all plants require access to both light and carbon dioxide to produce energy, grow and reproduce.

    en.wikipedia.org/wiki/Major_soil_deposits_of_India

    Soil deposit Description Image Alluvial soil Alluvial soil have been deposited by the Indus, the Ganges, and the Brahmaputra rivers. The entire northern plains (including parts of Arunachal Pradesh, Assam, Bihar (Almost entirely), Chandigarh, Delhi (almost entirely), Haryana, Himachal Pradesh, Madhya Pradesh, Punjab, Rajasthan, Uttarakhand, Uttar Pradesh, and West Bengal) are made of alluvial ...

  7. Photosynthesis system - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis_System

    Photosynthesis systems function by measuring gas exchange of leaves. Atmospheric carbon dioxide is taken up by leaves in the process of photosynthesis, where CO 2 is used to generate sugars in a molecular pathway known as the Calvin cycle. This draw-down of CO 2 induces more atmospheric CO 2 to diffuse through stomata into the air spaces of the ...

  8. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    The following is a breakdown of the energetics of the photosynthesis process from Photosynthesis by Hall and Rao: [6]. Starting with the solar spectrum falling on a leaf, 47% lost due to photons outside the 400–700 nm active range (chlorophyll uses photons between 400 and 700 nm, extracting the energy of one 700 nm photon from each one)

  9. Fractionation of carbon isotopes in oxygenic photosynthesis

    en.wikipedia.org/wiki/Fractionation_of_carbon...

    Carbon on Earth naturally occurs in two stable isotopes, with 98.9% in the form of 12 C and 1.1% in 13 C. [1] [8] The ratio between these isotopes varies in biological organisms due to metabolic processes that selectively use one carbon isotope over the other, or "fractionate" carbon through kinetic or thermodynamic effects.
