Question

Describe the anatomy of C4 plants. How does this anatomy reduce the occurrence of photorespiration​

Answer 1

Answer:

C4 plants largely bypass photorespiration by using an extension of the Calvin-Benson cycle to pump only CO2, and not oxygen, into the bundle sheath cells where the RUBISCO reaction occurs. C4 plants can maintain a high, local concentration of CO2 for RUBISCO activity without raising cellular oxygen levels.
