(i) Special leaf anatomy

(ii) Tolerance to high temperature

(iii) Responsive to high light intensity

(iv) Lack of photorespiration

(v) Greater productivity

How many of the following are associated with C₄ plants ?       

Due to their reduced rate of photorespiration and high rate of photosynthesis, C₄ plants are more efficient than C₃ plants. Due to the higher concentration of carbon dioxide in the bundle sheath cells, photorespiration is minimized.C₄ plants possess special leaf anatomy called ‘Kranz anatomy’ and undergo the C₄ pathway of photosynthesis.
