Animal cells do not need a cell wall because they have a flexible outer layer called the cell membrane that helps them keep their shape. They also don't need a central vacuole because they have smaller vacuoles scattered throughout the cell that help store and transport nutrients. These cells work together to do important things like move, eat, and grow without needing a cell wall or central vacuole to help them out. Overall, animal cells are cool because they have everything they need to do their job without those extra parts!
