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.
Animal cells have lysosomes, vacuoles, ER, Golgi body, mitochondria, cell membrane, nucleus, nucleolus, nuclear membrane, and ribosomes. They are ten times bigger than prokaryotic cells and have membrane covered organelles unlike prokaryotic. I made the cell by folding paper to form an animal cell and then gluing it.
