    The \[{{C}_{4}}\] plants are photosynthetically more efficient than \[{{C}_{3}}\] plants because:

    A) the \[C{{O}_{2}}\] compensation point is more

    B) \[C{{O}_{2}}\] generated during photorespiration is trapped and recycled through PEP carboxylase

    C) the \[C{{O}_{2}}\] efflux is not prevented

    D) they have more chloroplasts

    Correct Answer: C

    Solution :

    [c] The \[{{C}_{4}}\] pathway allows photosynthesis to occur at very low concentrations of carbon dioxide as PEP carboxylase has an extremely high affinity for carbon dioxide. This pathway also works well at high temperatures and light intensity, enabling efficient photosynthesis in tropical plants.
