Rod, one of two types of photoreceptive cells in the retina of the eye in vertebrate animals. Rod cells function as specialized neurons that convert visual stimuli in the form of photons (particles of light) into chemical and electrical stimuli that can be processed by the central nervous system.What are rods and cons?
Rods vs. Cones Cons are the cone shaped photoreceptors, whereas rods are the rod-shaped Cones provide the vision in the bright light (daylight) while rods provide the vision in the dim light (night). Rods contain the pigment rhodopsin, which is made up of the Vitamin A, on the other hand, cones contain the pigment iodopsin.What is the main function of rod cells?
What You need To Know About Rods/ Rod Cells Rods are a road-shaped, light-sensitive cell which lies on most peripheral parts of the retina in the vertebrate eye. ... Rod cells are cylindrical and comparatively longer than cone cells. Rod cells help in scoptic vision (low light vision) and night vision. The outer segments of rod cells contain rhodopsin as the visual pigment. ... More items...What do rods detect?
Rods, which can only detect differences between light and dark, are much more sensitive to light than the cones, which detect colour. When you look directly at something light from that object falls on an area predominately made up of the less sensitive cones.
