Which of these is not the part of the eye?

The cochlea is not a part of the eye; it is a part of the inner ear. The inner ear is responsible for hearing, while the eye is responsible for vision. The conjunctiva, cornea, and iris, on the other hand, are all parts of the eye. The conjunctiva is a thin, clear membrane that covers the white part of the eye and the inside of the eyelids. The cornea is the clear, dome-shaped layer that covers the front of the eye, while the iris is the colored part of the eye that controls the size of the pupil and the amount of light that enters the eye. In summary, the cochlea is not a part of the eye; it is a part of the inner ear. The conjunctiva, cornea, and iris are all parts of the eye that are responsible for different functions related to vision.
