how do the nearly transparent layers of a large white onion work together to give the onion a white appearance?
If you peel apart a large white onion, you will find that it contains many nearly transparent layers. How do these layers work together to give the onion a white appearance?

In the same way as a sheet of paper held up to a source of light, you can see light through 1 or more sheets. However if there are enough sheets packed together the light will not pass through. Like holding up a phone book to the sun and trying too look through it and see the sun. Each layer of the onion will stop some light from getting through up to a point where all of the light is stopped from passing through the onion, this means that the light is reflected back and appears non transparent. I know this is the other way round to the phone book analogy, however it is the same kind of effect. Hope this is of some help.
