Final answer:
Not having a cell wall provides flexibility and movement for animal cells. Animal cells can change shape, undergo cell division, and communicate with each other.
Step-by-step explanation:
Not having a cell wall is advantageous to animals because it allows for greater flexibility and movement. The absence of a cell wall allows animal cells to change shape and enables them to undergo processes such as cell division and phagocytosis. For example, white blood cells can change their shape to engulf and destroy foreign substances in the body. Additionally, the lack of a cell wall allows for communication between animal cells through the formation of specialized structures called gap junctions.
