Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. teristics ofthe crucifer, Moricandia arvensis, are intermediate betweenthoseof C3 and C4plants(I, 8,9, 17) and are strikingly similar to related features of the C3-C4 intermediate species,Cited by: The upregulation of genes related to Calvin cycle and ppdK promoted carbon fixation in both C3 and C4 photosynthetic pathways. The reallocation of carbon was also enhanced under 15% CO2.   Cyanobacteria are oxygenic photosynthetic harvest the sun's energy, absorb carbon dioxide, and emit oxygen. Like plants and algae, cyanobacteria contain chlorophyll and convert carbon dioxide to sugar through carbon fixation. Unlike eukaryotic plants and algae, cyanobacteria are prokaryotic lack a membrane bound nucleus, chloroplasts, and .

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (), "light", and sunthesis (σύνθεσις. Photosynthesis - Photosynthesis - The process of photosynthesis: carbon fixation and reduction: The assimilation of carbon into organic compounds is the result of a complex series of enzymatically regulated chemical reactions—the dark reactions. This term is something of a misnomer, for these reactions can take place in either light or darkness. The gas exchange of carbon dioxide and oxygen occurs through small, regulated openings called stomata (singular: stoma), which also play roles in the regulation of gas exchange and water balance. The stomata are typically located on the underside of the leaf, which helps to minimize water loss due to high temperatures on the upper surface of. The models further predict distinctive gas-exchange patterns with respect to the CO 2 compensation point and in the C 3-C 4 intermediate species Moricandia arvensis. Planta – CrossRef Google Scholar.

The steady-state photosynthetic gas exchange of the leaves was measured when the adaxial or abaxial surface was exposed to constant high light (1, μmol m −2 s −1; ad-con irradiation or ab. The oxidative photosynthetic carbon cycle (or C 2 cycle) is the metabolic pathway responsible for photosynthetic oxygen uptake and the light‐dependent production of carbon dioxide that is termed photorespiration. The C 2 and reductive C 3 cycles coexist, and combined, represent total photosynthetic carbon metabolism. A brief historical review is presented beginning with the early.   Photosynthesis is a highly regulated, multistep process. It encompasses the harvest of solar energy, transfer of excitation energy, energy conversion, electron transfer from water to NADP +, ATP generation and a series of enzymatic reactions that assimilate carbon dioxide and synthesize carbohydrate..
