Plz solve Q no. 5 plz fast a) b) c) Why photorespiration is not scen in C. plants ? Which is the most abundant enzyme in the world ? Explain the anatomical features found in the leaves of C, plants with diagram.

Dear Student,

Please find below the solution of your asked query:

(a) C₄ plants like sugarcane have evolved to avoid the wasteful process of photorespiration unlike C₃ plants. C₄ plants fix carbon dioxide in mesophyll cells and then this fixed carbon in form of 4 carbon compounds namely malate or aspartate is shuttled to bundle sheath cells.

(b) RuBisCO (RUBP carboxylase - oxygenase) is the most abundant enzyme in the world and present in very high concentration in chloroplasts. It is required in very high concentration for Photosynthesis.

For rest of the solutions we request you to ask different questions in different threads.

Looking forward to hearing from you again!
