Animal cells do not require a cell wall because they have a flexible plasma membrane that provides structure and support. The absence of a cell wall allows animal cells to be more adaptable and flexible in shape. Additionally, animal cells do not need a central vacuole because they do not need to store large amounts of water or nutrients like plant cells. Instead, animal cells have smaller vacuoles that are used for storage and transportation of molecules within the cell. Overall, the unique structure and functions of animal cells make a cell wall and central vacuole unnecessary for their survival and functioning.
