Animal cells do have vacuoles, but they are smaller, larger in number (plant cells usually have just one or a few large vacuoles) AND serve a somewhat different purpose than those of plants.
Answer by Beemusic. Confidence votes 433. Vacuoles in animal cells store food, water, waste, and minerals like plant cells. The only difference is that plant cells have larger vacuoles than animal cells.lant cells have one large vacuole, which plays an important role in the rigidity and turgor pressure of the cell. Animal cells do not need the same kind of function from th â¦ eir vacuoles, so the size and number of vacuoles in different cells will differ (depending on the type of cell).
