Answers

LIGHT REACTION:

During light reaction of photosynthesis chrophyll molecules absorb light energy and splits water into hydrogen and oxygen.Two compounds NADP and ATP are produced.

DARK REACTION:

Using NADP and ATP , carbondioxide is fixed into starch during the dark reaction.

Sunlight is needed only for the light reaction and dark reaction takes place in both light and darkness.

Hope it helps! :)
