If animals had cell walls in the same way plants do, they would be incapable of movement. Plant cell walls provide structure to the cell, and to the plant. Like animal cells, plant cells are eukaryotic cells, but with distinguishing features, including chloroplasts, cell walls and intracellular vacuoles.
Plant cell have the cell wall to protect from outside cell.
A cell is the smallest unit of life. Some other cells such as bacteria have cell walls as well, although bacterial cell walls are formed from different materials. Unlike animal cells, however, plant cells also have a cell wall that surrounds the cell membrane. The reason why animals do not have cell walls is so that we are flexible enough to move around (which plants do not need to do).
