Animal cells do not require a cell wall because they rely on other structures, such as the extracellular matrix and cytoskeleton, for support and shape maintenance. The lack of a cell wall also allows for greater flexibility and movement. Additionally, animal cells do not need a central vacuole because they have multiple smaller vacuoles distributed throughout the cytoplasm that perform various functions, such as storage of nutrients, waste products, and water regulation. Overall, these adaptations enable animal cells to carry out their functions efficiently without the need for a cell wall or central vacuole.
