Animal cells do not require a cell wall because they have a flexible cell membrane that provides structure and support while allowing for cell movement and communication. Additionally, animal cells do not need a central vacuole because they regulate water balance and store nutrients through smaller vacuoles scattered throughout the cell. The absence of a cell wall allows for more flexibility and adaptability in animal cells, enabling them to take on various shapes and functions. Overall, the structures and functions of animal cells are well-suited for their specific needs and roles in multicellular organisms.
