Which option correctly matches a receptor and its stimulus?
Answer and explanation
Correct answer: Retina and light
A receptor is a specialised cell or sensory structure that detects a particular stimulus and converts it into a nerve signal. The retina contains photoreceptors, namely rods and cones, that respond to light entering the eye. Hence, “retina and light” is the correct match. The tongue mainly detects taste, the ear detects sound, and the nose detects chemical odours, so the other pairings are mismatched.
