Description: Rods and cones contain photopigments necessary for the absorption of light that will initiate the events that lead to production of a receptor potential. Rods contain only rhodopsin. Cones contain three different photopigments, one for each of the three types of cones (red, green, blue). Photopigments respond to light in a cyclical process.
