In an anology of a house, what is a similar function to cell vacuoles?
Probably the best analogy of a cell vacuole to a house is a storage closet or storage room. The vacuole is an organelle with a surrounding membrane that contains any number of things including water, enzymes, food, or waste products. The cell can store items in the vacuoles for eventual use or for removal from the cell. In a similar fashion, a storage room in a house usually keeps a wide variety of items. Some of these items will be used later on, but a great many of them will eventually be thrown out.
