Photosynthesis
Complex process that takes place in living green plant cells. Radiant energy from the sun is used to combine carbon dioxide (CO2) and water (H2O) to produce oxygen (O2) and simple nutrient molecules, such as glucose (C6H12O6). See carbon sequestration. (source: EPA) Background from Wikipedia The leaf is the primary site of photosynthesis in plants. Photosynthesis (photo=light, synthesis=putting together), generally, is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a waste product. It is arguably the most important biochemical pathway known; nearly all life depends on it. It is an extremely complex process, comprised of many coordinated biochemical reactions. It occurs in higher plants, algae, some bacteria, and some protists, organisms collectively referred to as photoautotrophs. This article summarizes some of the major aspects of the process and provides links to more detailed articles explaining the numerous technical details, and implications, involved.
