NEETBiologyPhotosynthesis in Higher PlantsMCQ+4 / −1
The C4 plants are photosynthetically more efficient than C3 plants because
- Athe CO2 efflux is not prevented
- Bthey have more chloroplasts
- Cthe CO2 compensation point is more
- DCO2 generated during photorespiration is trapped and recycled through PEP carboxylase.
View written solutionFree
Correct answer: B
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.
