Research: Photosynthesis is the process by which chlorophyll containing organisms (green plants, algae, and some bacteria) capture energy in the form of light and convert it to chemical energy. Virtually all the energy available for life in the earth's biosphere (the zone in which life can exist) is made available through photosynthesis. A quite general, unbalanced chemical equation for photosynthesis is CO2 + 2H2A + light energy ? CH2 + H2O + H2A The formula H2A represents a compound that can be oxidized, which means, electrons can be removed. CO2 is carbon dioxide and CH2 is the hydrocarbons incorporated by the growing organism. In the vast majority of photosynthetic organisms such as, algae and green plants, H2A is water (H2O) but in some photosynthetic bacteria H2A is hydrogen sulfide (H2S). Photosynthesis involving water is the most important and best understood by scientists today. I have explained it in detail below. Photosynthesis consists of two...
