Sclera - It is a fibrous protective layer of the eye. It provides resistance to internal and external force.
Suspensory ligaments - holds the lens in place
Viteous humor - provides structural support to the eyeball. It is clear, thus, allowing light to reach the retina.
They are 'structural' because they function to support the structure of the eye - it holds the parts in place, gives the eye its shape and protects the eye, itself.
A 'functional' component, on the other hand, contributes to the main function of the eye, which is sight. It inludes the lens, retina, optic nerves, rods and cones.

The vitreous humor fills the inside of the eye ball and keeps the ball inflated, like the water in a water balloon. Without it it collapses.
The suspending ligaments hold the lens in place. A little like the ends of a hammock.
The sclera makes up the outside of the eye ball that makes up the actual shape.
