-
The C4 plants are photosynthetically more efficient than C3 plants because :
-
- the CO2 compensation point is more
- CO2 generated during photorespiration
- the CO2 efflux is not prevented
- they have more chloroplasts
Correct Option: C
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.
