Webrods and cones: cones are much better than rods to detect light ﬂickering at high frequency and probably suitable to see an object moving quickly. Phototransduction cascade is similar between rods and cones: the molecules involved in the cas-cade are functionally similar. However, the molecules themselves are distinct in many of the animals.3 For WebIn the retina of vertebrates the rods and cones have photopigment-bearing regions (outer segments) composed of a large number of pancakelike disks. In rods the disks are closed, but in cones the disks are partially open to the surrounding fluid. In a typical rod there are about a thousand disks, and each disk holds about 150,000 rhodopsin molecules, giving …
