    Question

    Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R

    Assertion A: Theoretically, a planophile canopy would be more efficient if radiation were distributed more evenly over leaf surfaces.

    Reason R: Such an equitable distribution could be accomplished by having leaves, at least the upper leaves, at a vertical leaf inclination when the sun is at high elevations.

    In light of the above statements, choose the correct answer from the options given below

    A Both A and R are true and R is the correct explanation of A Correct Answer Incorrect Answer
    B Both A and R are true but R is NOT the correct explanation of A Correct Answer Incorrect Answer
    C A is true but R is false Correct Answer Incorrect Answer
    D A is false but R is true Correct Answer Incorrect Answer

    Solution

    A planophile canopy consists of leaves that are oriented horizontally or nearly horizontally. If radiation is evenly distributed over the leaf surfaces, it ensures that all the leaves receive an optimal amount of sunlight for photosynthesis, resulting in more efficient light capture and utilization by the canopy. Vertical leaf inclination allows the leaves to intercept sunlight from different angles, reducing shading between leaves and ensuring a more equitable distribution of light energy among the leaves of the planophile canopy.
