The chloroplast is the organelle responsible for photosynthesis in eukaryotic cells. In chloroplasts
the light independent reactions require water as the initial reactant
the light independent reactions occur in the inner membrane area
the final product of the light reaction is glucose
the light reactions occur in the grana
