Photosensitive compound in human eye is made up of
Rhodopsin is found in
Rhodopsin is found in specialized light receptor cells called rods. These are light-sensitive tissue present in the retina. They provide vision in low light. Other light receptor cells in the retina, called cones, are responsible for vision in bright light.
Thus, the correct answer is 'rods only.'
