Which adaptation enhances carboxylation efficiency in hot, arid C4 plants?

💡 Explanation

Under arid conditions, spatial separation via the C4 pathway concentrates CO2 in bundle sheath cells through PEP carboxylase action, preventing photorespiration by Rubisco. Therefore spatial separation boosts efficiency, rather than temporal techniques like CAM, increased water loss from stomata, or direct photorespiration reduction in mesophyll cells.
