http://www.factmonster.com/cig/biology/fluid-mosaic-model-membrane-structure-function.html This article may also help while you're waiting for someone to answer your question. It is very informative on the fluid mosaic model... and it has a paragraph in it regarding the type of molecule that can move passively across the membrane without the aid of protein :)

I think this is more of a biology question but, small molecules for sure like water and O2 and CO2 I believe. Try this: http://en.wikipedia.org/wiki/Passive_transport
