  1. The carbon and oxygen come from carbon dioxide in the air, while the hydrogen comes from water, either from the air or more typically from the ground via roots. 

    _x000D_

    The overall equation looks like this: 

    _x000D_

    6 CO2 + 6 H2O = C6H12O6 + 6 O2 

    _x000D_

    Of course, this takes sunlight as energy since it is a reduction reaction, and it is actually a multiple-stage reaction in chloroplasts (or other bodies for certain simpler plants) that uses light to alter chlorphyl, and then uses the altered chlorophyll to make ATP or other energy-storing compounds, which in turn are used to steal electrons from water, convert the CO2 into carboxyl, and rearrange things to make sugar. 

    _x000D_

    Why would a plant make sugar instead of just using the ATP directly? The sugar is more stable and more easily transported (and starch or cellulose is yet more stable), so the plant gives up some energy to make an energetic substance that is easier to use._x000D_
