Basically the chemical formula for photosynthesis is CO2 + H20 + sunlight = C6H12O6 (glucose; sugar) + water + oxygen (waste gas).

Photosynthesis takes water, sunlight and carbon dioxide to produce the sugar that runs the plant, a little water and oxygen are the remaining products, oxygen is a waste gas.

According to Wikipedia:
“Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water, the energy source is sunlight, and the end-products include glucose and oxygen. It is arguably the most important biochemical pathway.”

Photosynthesis uses light energy and carbon dioxide to make triose phospates (G3P). G3P is generally considered the prime end-product of photosynthesis. It can be used as an immediate food nutrient, or combined and rearranged to form monosaccharide sugars, such as glucose, which can be transported to other cells, or packaged for storage as insoluble polysaccharides such as starch.

A general equation for photosynthesis is:

6 CO2(gas) + 12 H2O(liquid) + photons → C6H12O6(aqueous) + 6 O2(gas) + 6 H2O(liquid)

carbon dioxide + water + light energy → glucose + oxygen + water

When written as a word equation the light energy appears above the arrow as it is required for photosynthesis but it is not actually a reactant.

The equation is often presented in introductory chemistry texts in simplified form as:
6 CO2(gas) + 6 H2O(liquid) + photons → C6H12O6(aqueous) + 6 O2(gas)

Photosynthesis occurs in two stages. In the first phase light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of carbohydrates.”

The chemical reaction is actually interchangeable, apart from the fact that photosynthesis uses sunlight and that energy is released in the form of ATP in cellular respiration. Either way its still energy no matter what form it is. Its significant because it shows how the producers of this world provide the consumers with energy. If there was no existence of photosynthesis or cellular respiration, there would not be the existence of life in theory. Except for chemosynthesis I suppose, but that's a little different and I can't be bothered explaining. Btw, to the person who answered above me. Did you copy that off wiki or do you enjoy writing essays or something cause honestly trying to read that just makes my head spin @.@
