Options
- Aare rich in PEP carboxylase
- Black RuBisCo
- Clack both RuBisCO and PEP carboxylase
- Dare rich in RuBisCO.
Correct answer
D. are rich in RuBisCO.
Step-by-step solution
In C ₄ plants with Kranz anatomy, the mesophyll is undifferentiated and its cells occur in concentric layers around vascular bundles. The vascular bundles are surrounded by several layers of specialized large sized cells called bundle sheath cells. The C ₄ cycle involves two carboxylation reactions, one taking place in chloroplasts of mesophyll cells and another in chloroplasts of bundle sheath cells. In C ₄ plants, the first step of carbon dioxide fixation takes place in the chloroplasts of mesophyll cells contain
