The cell wall protects and supports the plant cell. but IS NOT the same thing as the cell membrane .
The Cell Wall Protects the Inner Cell and It Helps so the Cell can Reproduce and survive While on land and Not die off.
I assume you really mean, "What structure does a plant cell have that an animal cell does not?"Plant cells have a cell wall. Animal cells do not.
The plant cell is actually just like tiny bricks that make up the house which is the plant, so it isn't in a certain place of the plant, it is the plant (well at least in tiny pieces).
