What type of sensory receptor allows detection light and vision?
Photoreceptors are specialized sensory cells that are sensitive to light and are responsible for detecting and converting light into electrical signals. These signals are then transmitted to the brain, which interprets them as visual images. There are two main types of photoreceptors: rods and cones. Rods are more sensitive to low levels of light and are responsible for vision in dim light conditions, while cones are more sensitive to colour and are responsible for colour vision and visual acuity in bright light conditions.
