Difference between cone cell and rod cell of eye in human body?

Answer 1

Rod cells pair one neuron with many light receptor cells. The functional result is that they detect under much lower light conditions, but only in grayscale, e.g. black, white, grey. They also detect movement more readily, but not as sharply as cones will. They're located so that your peripheral vision is mostly based on rods -- this is why you can see things in low light conditions at the periphery of your vision and not straight ahead. Cones are one nueron and one light receptor. Centered in the eye, there are three types of cones: those that react to colored light we call Magenta, Cyan and Blue (those familiar with light will know that with these three, you can create any visible color of light). Cones resolve better, more sharply, and allow for color vision.
