Bioethanol

Bioethanol, what is bioethanol? is it the same with ethanol? is it an alcohol? Well from what i've read is bioethanol is ethanol obtained from fermentation of material containing starch or sugar such as cassava and molasses. This "Plant Oil" or PO is used to substitute gasoline. Ethanol that can be used as PO is pure, free of water, alcohol (anhydrous alcohol) with 99.5% rate. This fuel then called fuel grade ethanol (FGE). The mixture of FGE and gasoline is called gasohol in my country.
But I have question on that "Plant Oil" term, I think maybe it is used for biodiesel. Biodiesel is from oil so it can be called "Plant Oil" but for bioethanol??? Bioethanol is not from oil...
