Orchidee photosynthesis
WebJun 18, 2024 · Abstract. Aerosol- and cloud-induced changes in diffuse light have important impacts on the global land carbon cycle, as they alter light distribution and photosynthesis in vegetation canopies. However, this effect remains poorly represented or evaluated in current land surface models. Here, we add a light partitioning module and a new canopy light … WebThe basic chemical reaction for oxygenic photosynthesis is: CO 2 + 2H 2 O + photons → [CH 2 O] + O 2 + H 2 O. During photosynthesis, one molecule of carbon dioxide and 2 molecules of water are converted into molecular oxygen and some carbohydrate. Creating organic compounds from inorganic carbon is known more generally as “carbon fixation.”.
