What does the root 'corne' or 'kerat' refer to?

Cornea
Eye
Pupil
Iris

The correct answer is: Cornea

The root 'corne' or 'kerat' refers specifically to the cornea, which is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. This structure plays a crucial role in focusing light and providing protection for the internal components of the eye. The terms 'cornea' and 'kerat' are both derived from Greek and Latin roots that emphasize its connection to the eye's anatomy, specifically related to this clear outer layer. The other choices refer to different parts of the eye: 'eye' is too broad and encompasses all its structures, 'pupil' refers specifically to the opening that allows light to enter, and 'iris' is the colored part of the eye surrounding the pupil. Each term has distinct roots not directly related to 'corne' or 'kerat'. Thus, the correct identification for the root in question aligns with its specific anatomical reference to the cornea.
