The ability of plants to photosynthesize lets all life on earth exist. Plants capture and store the energy of the sun in the form of highly structured carbohydrates, and also provides oxygen that animals breathe in:

6CO2 + 6H2O + Energy from the sun ® C6H12O6 + 6O2

C stands for carbon, O for oxygen, and H for hydrogen;               carbon dioxide + water in the presence of energy from the sun yields carbohydrates and oxygen.

Respiration, or the release of energy when carbohydrates are broken down, is the opposite equation:

C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy

I couldn't get the subscripts to work properly, but the numbers after the elements are supposed to be lower, and indicate the number of atoms of each; see the link if that is not clear.

6 CO2 + 12 H2O C6H12O6 + 6 O2 + 6 H2O

But because water is both a reactant and a product, the equation can be simplified accounting for net water consumption, which is

6 CO2+ 6 H2O C6H12O6+ 6 O2

Carbon dioxide + Water + Light energy → Glucose + Oxygen

This is a redox reaction. In this reaction the oxidation of H2O occurs and reductioN OF CO2 takes place.Basically its a reverse of respiration.

Photosynthesis is a redox process. Here is the equation:

Energy + 6CO2+ 6H20=>C6H12O6 + 6CO2

In this equation, 6CO2 becomes reduced to C6H12O6, and 6H20 becomes oxidized to 6C02.

The equation for photosynthesis is:

6CO2 + 6H2O + Energy - - > C6H12O6 + 6O2

basically the equation for photosynthesis is :

carbon + water + energy ( sunlight ) - - > Sugar + oxygen

* The equation for photosynthesis is also the reverse equation for cellular respiration
