Cell wall is that plant cell organelle which supports and maintains the cell's shape and protects the cell from the damage.
It is a thick and fibrous structure, made of cellulose, which encloses the cell in it, acting as a boundary between the components of the cell and the external environment.
The cell wall is present in plants, algae, fungi and prokaryotes.
Plant-cell organelles do not have cell membranes. Perhaps the second answer was just a mistaken spelling of cell wall. The cell wall helps cells maintain shape and protects them from damage.
Explanation:
Plant-cell organelles have a cell wall for this purpose. Animals have cell membranes that provides the same protection for their cells.
