Verified step by step guidance

Begin by understanding the function of photoreceptors. Photoreceptors are specialized cells in the retina of the eye responsible for detecting light stimuli and converting them into electrical signals that can be processed by the brain.

Next, consider the location of photoreceptors. They are primarily located in the retina, not the olfactory epithelium, which is involved in the sense of smell.

Evaluate the involvement of photoreceptors in detecting sound waves. Photoreceptors are not involved in sound detection; this function is performed by hair cells in the cochlea of the inner ear.

Understand the classification of photoreceptors. They are not mechanoreceptors, which are responsible for detecting mechanical changes such as pressure or vibration. Photoreceptors are a type of sensory receptor specifically for light.

Conclude by identifying the correct statement: Photoreceptors are responsible for detecting light stimuli, which is their primary function in the visual system.
