Animal cells do not require a cell wall because they have a flexible cell membrane that provides support and shape to the cell. Additionally, animal cells do not need a central vacuole because they have smaller vacuoles that serve specific functions such as storing nutrients, regulating cell processes, and breaking down waste products. The absence of a cell wall and central vacuole allows animal cells to be more dynamic and adaptable to changing environments. Lastly, animal cells rely on other structures such as cytoskeleton proteins and extracellular matrix for maintaining cell structure and function.
