Which of the following statements accurately describes a major difference between plant cells and animal cells?

Animal cells provide rigidity to plants, while plant cells do not have this function.

Animal cells maintain shape through cell walls, unlike plant cells.

Plant cells have cell walls, while animal cells do not. (correct)

Plant cells lack a membrane inside the cell wall, unlike animal cells.
