Photosynthesis is actually oxidation reduction process in which water is oxidised and CO2 is reduced to carbohydrates.
Both ATP and NADPH2 are required for reduction of CO2. But this reduction is independent of light, ie, it occurs in presence or absence of light. Hence, it is known as light reaction and light independent part is known as dark reaction. It occurs in stroma of chloroplast. Also known as Blackman's reaction.
