Rods are very sensitive and enable vision in dim light conditions, whereas cones mediate daylight vision and color detection. In photoreceptors, absorption of photons causes conformational change and activation of visual pigment rhodopsin which in turn activates signalling cascade that leads to biochemical, electric and secretory cell response.
