Animal cell can't move why

The T cells are part of the immune system and must therefore be able to reach the tissue that has been exposed to, for instance, a bacterial invasion. To be able to move, the cell must attach itself to a surface and use its front to push to exert the force it needs. Cell movement is a necessary function in organisms. Without the ability to move, cells could not grow and divide or migrate to areas where they are needed. The cytoskeleton is the component of the cell that makes cell movement possible.

Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones.

the correct answer would be d. hope this !
