Q.
Following table summarises the differences between light reactions and dark reactions.
Light reaction
Dark reaction
(i)
These are also called as biosynthetic phase.
These are also called as photochemical phase.
(ii)
These reactions occur over thylakoids.
These reactions occur in stroma of chloroplasts.
(iii)
These produce assimilatory power i.e., $NADPH_{2}$ and $ATP$.
These consume $NADPH_{2}$ and $ATP$.
(iv)
These are directly dependent upon light.
These depend upon the products synthesised during light reactions.
Which of the above pairs of differences is/are incorrect ?
