    Which crop utilises solar energy most efficiently?

    A)  Potato                                

    B)  Sugarcane

    C)  Wheat                                

    D)  Rice

    Correct Answer: B

    Solution :

                     \[{{C}_{4}}\]plants utilise solar energy most efficiently. Because photosynthesis rate is very high in \[{{C}_{4}}\] plants e.g., Sugarcane, maize etc. In \[{{C}_{4}}\]plants, carbon fixation occurs in mesophyte cells and \[C{{O}_{2}}\]is then concentrated in   bundle sheath cells, inhibiting photorespiration and increasing carboxylarion efficiency.
