Question

why is it an advantage for most leaves to be broad and thin​

Answer 1

Answer:

These organs are broad and flat to allow for efficient light harvest. The leaves are broad to maximize surface area for light harvest and they are thin since light cannot penetrate too deeply into the leaf (the amount of light decreases exponentially with distance).
