This post had me doing some research. And I admit I didn't know exactly how Cashews grow. I don't know if I can attach pictures in the comments area (if you can, would someone help me) but I'll attach a link to the Huffington Post of all places...
Each individual cashew inside of its shell grows attached to a false fruit off a tree. It's quite the interesting sight! I suggest checking it out.
