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.
Plant 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).he vacuole cell is in plants (edit) The vacuole is not a cell, but it is found within both the plant and animal cells. The vacuole is an organelle that can be found in both â¦ plant cells and animal cells, and have different functions for each. Answered. In Zoology or Animal Biology.
