What is the actual equation for Photosynthesis?

Description of photosynthesis (plants) chemical equation?

• I am stuck on this and need some help. I require to write a brief description of the chemical equation of photosynthesis...this is what I have. Balanced chemical equation for photosynthesis: 6CO2 + 12H2O + light energy ==> C6H12O6 + 6O2+ 6H2O Word equation: carbon dioxide + water + light energy ==> produces glucose + oxygen + water Process description in words: Photosynthesis is the conversion of light energy into chemical energy by living organisms. Carbon dioxide is where the process of photosynthesis begins. Without carbon dioxide present photosynthesis would not occur. The gas exchange of carbon dioxide and produced oxygen exchange occur in the pore of the leaf, called the stomata (stoma). The stomata is a leaf pore which is located on the skin of the leaf, much like a pore on the human body. The pore expands and opens, taking in a water supply. Water can also be absorbed through the roots of the plants, travelling upwards through the xylem to the leaves, and will occur when leaves experience a water loss. ,<<<<<------------- AM I DOING HIS RIGHT? HOW CAN I EXPLAIN THE REST? I DO NOT KNOW WHY I AM HAVING SO MUCH TROUBLE EXPRESSING THIS. THANKS.

• Answer:

  The equation is correct, but technically, you could just use 6 H2O in the reactants to show the equation overall, since water is present after the reaction as well, it can be cancelled out. However, photosynthesis is a completely separate process to gas exchange, water uptake and transpiration. You can say that the pigment chlorophyll absorbs light energy, which is then used to combine water and carbon dioxide to create simple sugars. That's not true to the exact details of the reaction, but it's a basic rundown of what happens. Also, water cannot be absorbed by leaves through the stomata, instead water just tends to evaporate out of the leaves (or other transpiring tissue) via stomata.
