Question

Rods and cones are located in the ____.  
A) lens
B) cornea
C) pupil
D) iris
E) retina

Accepted Answer

Rods and cones are photoreceptor cells that are located in the retina of the eye. The retina is the innermost layer of tissue in the eye, and is responsible for converting light into neural signals that are sent to the brain for visual processing. The other options (lens, cornea, pupil, and iris) are all parts of the eye, but do not contain rods and cones.
