Cones
Rods and cones.
Photoreceptor cells and Rod cells are the more known ones. These allow you to see color.
Cones are a special type of photoreceptor cell in the retina that allow you to see brighter light than "rods" (a different type of photoreceptor cell), particularly to see color. The brain interprets the response of cones to the different wavelengths of light in order to perceive color in this way.
Action spectra and photoreversibility experiments show that phytochrome is the pigment that receives the red light. Red light is the most effective color in interrupting the night-time portion of the photoperiod.
Rods are the photoreceptors that are not used in color vision. Rods are much more plentiful than the cones, and much more sensitive, they are responsible for scotopic vision.
i was scared to approach ya but then you came closer, hoping u would give me a chance!
photoreceptors
Most dogs cannot see in color, however, it has been discovered that some dogs can indeed see color. However, it is not as bright as humans, because dogs only have about 20% of the cone photoreceptor cells.
Cones help you see color and detail; rods see in black and white and detect movement in your peripheral vision.
A few light lines running straight across the page may mean that the photoreceptor is scratched. You should call the machine in for service.
Cone cells, or cones, are one of the two types of photoreceptor cells that are in the retina of the eye which are responsible for color vision as well as eye color sensitivity; they function best in relatively bright light, as opposed to rod cells that work better in dim light.
