1. Photosynthesis occurs at high temperatures (30-450C) in C4 plants. Hence they are functional at high temperatures.
2. Phospho-enol pyruvic acid is the most efficient CO2 acceptor in C4 plants.
3. Food production and transport is high due to the cranial anatomy of leaves.
4. Even if the concentration of CO2 is low, the trajectory of R can continue.
5. In C4 plants, respiration and photorespiration are low, so CO2 emission is high.
6. The C4 pathway remains active even though the stomata of frost plants are partially closed.
7. C4 plants carry some important adaptive traits. Due to these characteristics they can survive in tropical and arid regions.
