Explain why C4 plants are more efficient in photosynthesis than C3 plants
- In C4 plants carboxylation occurs at higher rate since PEP carboxylate is more efficient.
- C4 plants accumulate carbon dioxide internally in the bundle sheath cells; this increase the rate of carboxylation and photosynthesis
- Photorespiration does not occur in C4 plants because PEP carboxylase does not accept oxygen
- Light saturation in C4 plant occurs at higher light intensity than in C3 plants
