why do C4 plants show better in yield and high productivity than C3 plants? For 2 markquestion

Dear student

C4 plants show better in yield and high productivity than C3 plants because:-

• ​​​​​​​C4 plants have krantz anatomy as both bundle and mesophyll cells are present. The main objective of this is to increase CO₂ concentration near rubisco enzyme.
• In C4 plants photorespiration does not take place so CO₂ is not wasted.
