Photosynthesis and global warming
Photosynthesis can reduce the amount of carbon dioxide in the air. It represents a sink for carbon dioxide in the environment. Reducing forests and other vegetation can produce a net increase in atmospheric carbon dioxide. Therefore, more photosynthesis might act to reduce global warming. On the other hand, this is a more complicated title than it appears at first.
The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.
the reaction of this process:
6H2O + 12CO2 + S.E -----------------------> C6H12O6+
6O2 + 6H2O
Easily, we can explain the reaction like 6 molecules of water plus, 12 molecules of Carbon Dioxide plus Sun energy, cross with chlorophillian pigment, in the product we have glucose, plus oxygen, plus water. We can put so briefly the process saying that the organisms use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, The conversion of no usuable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and release the oxygen that we absolutely must have to stay alive
Importance of the photosynthesis:
Animals and plants both synthesize fats and proteins from carbohydrates; thus glucose is a basic energy source for all living organisms. The oxygen released (with water vapor, in transpiration) as a photosynthetic byproduct, principally of phytoplankton, provides most of the atmospheric oxygen vital to respiration in plants and animals, and animals in turn produce carbon dioxide...
