Which surface of the fern is shinier? Why?

The light-tolerant side of the leaf is also shiny, and this is because of a thick waxy cuticle. The shade-tolerant side of the leaf also has a cuticle but if we follow it logically, the light-tolerant side of the leaf needs more protection from heat evaporation because it's always being hit by light.

The upper surface of the fern is more shinier than the lower surface.
