Animal cells do not require a cell wall because they have an outer membrane called the plasma membrane, which provides structural support and protects the cell. This membrane is flexible and allows animal cells to change shape and move. Additionally, animal cells do not require a central vacuole because they obtain nutrients and eliminate waste through different structures such as lysosomes and the endoplasmic reticulum. These adaptations allow animal cells to perform their functions effectively without the need for a cell wall or central vacuole.
