Question

Quizplus · Accepted Answer

Photoreceptors are specialized cells that are found on the retina in the eyes of vertebrates, including mammals and humans. Invertebrates, on the other hand, have a variety of different structures for detecting light, such as simple eyes and compound eyes. The lens and cornea are structures that are involved in focusing light onto the retina, but they do not contain photoreceptors themselves. The iris is a structure that controls the amount of light that enters the eye, but it also does not contain photoreceptors.
