In vision, the sensory receptors are called?

• A. Ganglion cells
• B. Hair-cell receptors
• C. Bipolar cells
• D. Rods and cones

Answer: (D)

In vision, the sensory receptors responsible for detecting light and facilitating our ability to see are called rods and cones. These photoreceptor cells are located in the retina of the eye. Rods are highly sensitive to light and allow us to see in low-light conditions, but they do not provide color information. Cones, on the other hand, are responsible for color vision and function best in bright light conditions. Together, rods and cones convert light into electrical signals that are then sent to the brain for processing, ultimately allowing us to perceive visual images. The other options presented do not serve as the primary sensory receptors for vision. Ganglion cells and bipolar cells are part of the retinal structure but serve different roles in processing visual information rather than directly detecting light. Hair-cell receptors are associated with the auditory system, not vision, as they are found in the cochlea of the inner ear and are responsible for hearing rather than visual perception.
