All the statements accurately describe C4 plants. They fix CO2 into oxaloacetate (a 4-carbon compound) in mesophyll cells, require more energy for photosynthesis than C3 plants, typically have Kranz anatomy to facilitate their unique photosynthetic pathway, and produce a 4-carbon organic acid as the first stable product of photosynthesis.
