  2. C. B. van Niel - Wikipedia

    en.wikipedia.org/wiki/C._B._van_Niel

    The chemical summation of photosynthesis was a milestone in the understanding of the chemistry of photosynthesis. This was later experimentally verified by Robert Hill. In a nutshell, van Niel proved that plants give off oxygen as a result of splitting water molecules during photosynthesis, not carbon dioxide molecules as thought before.

  3. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Cornelis Van Niel made key discoveries explaining the chemistry of photosynthesis. By studying purple sulfur bacteria and green bacteria, he was the first to demonstrate that photosynthesis is a light-dependent redox reaction in which hydrogen reduces (donates its atoms as electrons and protons to) carbon dioxide.

  4. 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. [1]

  5. Plant cell - Wikipedia

    en.wikipedia.org/wiki/Plant_cell

    Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

    en.wikipedia.org/wiki/BSCS_Science_Learning

    The BSCS also expanded its work beyond standard tenth-grade biology curriculum to produce educational materials for exceptional students, for teachers, and for all educational levels, from kindergarten to adult. In 2018, BSCS celebrated its 60th anniversary and officially changed its name to BSCS Science Learning.

  7. Chlorophyll a - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll_a

    Chlorophyll a is very important in the energy phase of photosynthesis. Two electrons need to be passed to an electron acceptor for the process of photosynthesis to proceed. [5] Within the reaction centers of both photosystems there are a pair of chlorophyll a molecules that pass electrons on to the transport chain through redox reactions. [20]

    Sanders got the last word after his team's win, which improved his Colorado team to 5–2 overall and 3–1 in the Big 12. That ties the Buffaloes with Cincinnati for fourth place in the conference .

  9. Light-harvesting complex - Wikipedia

    en.wikipedia.org/wiki/Light-harvesting_complex

    Photosynthesis is a process where light is absorbed or harvested by pigment protein complexes which are able to turn sunlight into energy. [5] Absorption of a photon by a molecule takes place when pigment protein complexes harvest sunlight leading to electronic excitation delivered to the reaction centre where the process of charge separation can take place.
