The C 4 plants are more photosynthetically efficient than C 3 plants because:

The C 4 pathway allows photosynthesis to occur at very low concentration of CO 2 .

The CO 2 compensation point is more.

CO 2 generated during photorespiration is trapped and recycled through PEP carboxylase.

Choose the incorrect statement from the following:

C 4 acid OAA is formed in the bundle sheath cells

PEP carboxylase is found in the Mesophyll cells of C 4 plants

RUBP carboxylase is found in the bundle sheath cells of C 4 plants

Mesophyll cells lack RuBisCo enzyme

Following table summarises the differences between light reactions and dark reactions.

	Light reactions	Dark reactions
(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., $N A D P H_{2}$ and $A T P$	These consume $N A D P H_{2}$ and $A T P$
(iv)	These are directly dependent upon light	These depend upon the products synthesized during light reactions

Which of the above pairs of differences is/are incorrect?
