The upper surface of the fern leaves known as fronds are shiny as a result of

<h3>What is a Fern? </h3>
A fern is a type of vascular plant which doesn't produce flowers and
reproduces with the aid of spores. Ferns are mostly found in shaded areas
and have a characteristic shiny surface.
The shiny surface is however as a result of the production of waxy cuticles
by the epidermis of the leaves. The waxy cuticle helps to prevent the plant
from water loss.
