Yeast is a plant that needs sugars to produce the gas that causes "rising." it can be processed cane sugar, natural sugar like honey, or the simple sugars in the flour or other starches we use for baking to make it rise. An article I found indicates that warm water is necessary for some types of yeast1, but that is only to prepare the yeast to "eat" the sugars. You do need some moisture to enable the yeast, but it doesn't have to be water. Pouring yeast on a banana makes for a fun science experiment for kids. 1. How_can_you_make_yeast_rise
