C₄ plants reduce photorespiration by
- A
Performing the light reactions of photosynthesis only during the night
- B
Eliminating RuBisCO from their photosynthetic mesophyll cells entirely
- Ccheck_circle
Concentrating CO₂ in bundle-sheath cells before delivering it to RuBisCO
- D
Storing fixed CO₂ in solid crystalline form within bundle-sheath cells
Explanation
Mesophyll cells use PEP carboxylase to fix CO₂ into a 4-carbon intermediate, shuttling it to bundle-sheath cells where high CO₂ keeps RuBisCO operating efficiently.
