A plant avoids photorespiratory losses, has improved water use efficiency, shows high rates of photosynthesis at high temperatures and has improved efficiency of nitrogen utilization. To which physiological group does this plant belong?

Solution & Step-by-step Explanation

C_{4} plants (like maize, sorghum) have a special anatomy called Kranz anatomy. They possess a mechanism to increase the concentration of CO_{2} at the enzyme site, thus avoiding photorespiration. They are adapted to high temperatures and dry conditions.
