In photosythesis the water molecules splits then the electrons are excited used protons finally the the electrons are free and it will fues protons and forms water molecules.

In photo synthesis the main product is sugar along oxygen.

6 CO2 + 6 H2O - C6 H12 O6 + 6 O2

i.e., carbon-di-oxide when reacted with water molecules splits into glucose and oxygen

During phosynthesis plants takes CO2 and release O2 so, its CO2.

Generally three process occurs during photosynthesis it is 1. Absorption of light energy by chlorophyll second is conversion of light energy into chemical energy and splitting of water molecules into hydrogen and oxygen 3rd is conversion of light energy into chemical energy so it is possible.
