"WebAnimal cells do not have a cell wall (they can have a similar thing , called a cell cortex). So the vacuoles here play a more subordinate role - they still help with endo- and exocytosis. Also the are quite smaller than plant vacuoles and greater in number. And of course, there are some animal cells with no vacuoles at all. Hope that helps :) " - How might other eukaryotic cells move around
