Quiz: Color Cells Send Signals (Age 11)

1. 1

   What do the three color cells in the retina do when light hits them?

   • They store pictures so you can see them later.
   • They make the eye move to follow the light.
   • They turn light into color signals for the brain.
2. 2

   Where do the color signals go after the color cells send them?

   • To the colored part of the eye, where they mix.
   • To the muscles that move the eye.
   • Along nerve pathways to the brain.
3. 3

   Why can we see different colors?

   • Because each color cell sends the same signal to the brain.
   • Because red, green, and blue color cells send different signals to the brain.
   • Because color is made only by light, not by the eye or brain.
