Animal cells do not require a cell wall because they do not need the extra support and protection that a cell wall provides. They also do not need a central vacuole because they rely on other organelles, such as lysosomes and vesicles, to store and transport materials within the cell. Animal cells have a flexible cell membrane that allows them to change shape and move easily, which is why they do not need a rigid cell wall. Additionally, animal cells often have specialized structures, like cilia and flagella, that help them carry out their functions without the need for a central vacuole.
