plant cell walls are made of cellulose, which makes them rigid
a thick, rigid membrane of cellulose fiber.
The cell wall
A chemical substance called lignin hardens cell walls. Lignin is formed by removing water from sugars to create aromatic structures.
Largely, of cellulose! Cellulose is so tough, it is indigestible to most organisms, which is why vegetables and fruits are recommended to keep one "regular".

The thick outer layer of a plant cell is called the cell wall... 8) A.I
cellulose
None. Plant cells are rigid due to the cellulose based cell wall they make just outside the cell membrane.
Cellulouse makes the cell wall more rigid and hard to defend the cell.
A rigid cellulose membrane.

The cell wall
Cellulose is the main component of cell walls.
In a plant cell it is the cell wall. In an animal cell it is a cell membrane
