Question:
My question is dealing with the human eye. I'm aware that there is three kinds of cone cells, but I don't know if they are more sensative to light than the rods are or what and I need to know adzactly what colors each of the three cone cells are sensative to also. (thank you if you respond)

Replies:
Cone cells, which see colors, are less sensitive than rod cells, which see only black and white. Since rod cells respond to all wavelengths of light, but cones only respond to their specific color ranges, the rod cells can see in less total light.
