  • Rods are more in number around periphery of retina while cones are more concentrated near central part of retina, i.e. in macula. ... Both cells are packed with photoreceptive opsin proteins, rhodopsin in rod and iodopsin in cone . Both the cells get stimulated by light and develop electrical signal in response to light.
  • Rhodopsin (also known as visual purple) is a light-sensitive receptor protein involved in visual phototransduction. ... Rhodopsin is extremely sensitive to light, and thus enables vision in low-light conditions. When rhodopsin is exposed to light, it immediately photobleaches.
