ISO: Root of a Tapioca plant or cassava root?

I have a tapioca root or cassava root that I picked from a plant today.  How do I treat this and what can I make with it?  I have used yucca root, is this the same?  I looked it up and am confused because in some of the text it appeared that all I had to do was cook it like any other starchy root, and as I kept reading it instructed to drain the water because of chemicals the root has.  I am totally confused.  Also, can this root be stored for a period of time.
