Which statement best explains why animal cells do not require a cell wall or a central vacuole for their functions? Cell walls and central vacuoles work together to provide rigid support for plant cells and keep plants upright. Animal cells do not need to be rigid because animals have other means of support for their bodies. Cell walls are rigid, maintaining the plant cell shape, while central vacuoles provide outward pressure to keep plant cells firm.

Animal cells do not require a cell wall or central vacuole for their functions because they have a flexible cell membrane that provides support and protection. Additionally, animals have an internal skeletal system, such as bones or cartilage, that provides structural support for their bodies. This is in contrast to plant cells, which rely on cell walls and central vacuoles for structural support.
