The cell membrane gives strength to animal cells and the cell wall gives strength to plant cells.
By definition, animal cells have no cell wall -- only plant cells do. That being said, the major function of the cell wall in plant cells is to control cell pressure due to the influx and exit of water into and out of the cell. Turgor in the plant cell is part of what gives a plant structure and helps it "stand up." Animal cells do not need this characteristic, as they have other mechanisms for maintaining structure and shape.
