Class 11 NEET Biology Photosynthesis in Higher Plants

Plants exhibiting characteristic kranz anatomy are C4 plants. Spatial separation of carbon dioxide fixation and RUBISCO activity in mesophyll and bundle sheath cells of C4 plants respectively avoids photorespiration by concentrating CO2 in bundle sheath cells to scale down the oxygenase activity of RUBISCO and increase the RUBISCO efficiency. Maize is C4 plant while papaya, peas, potato are C3 plants. So, the correct answer is option D
