The c₄ plants are photosynthetically more effficient than C₃ plants because:

The c₄ plants are photosynthetically more efficient than C₃ plants because:

Options

(a) the CO₂ compensation point is more
(b) CO₂ generated during photorespiration is trapped and recycled through PEP carboxylase
(c) the CO₂ efflux is not prevented
(d) they have more chloroplasts

Correct Answer:

the CO₂ efflux is not prevented

Explanation:

The C₄ pathway allows photosynthesis to occur at very low concentrations of carbon dioxide as PEP carboxylase has an extremely high affinity for carbon dioxide. This pathway also works well at high temperatures and light intensity, enabling efficient photosynthesis in tropical plants.
