Six facts about
the cell wall
Cell walls are made of cellulose. They are a
feature of plant cells.
Mature cells add substances to the primary cell
wall for additional strength or to make it waterproof.
This is the secondary cell wall.
The cell wall is rigid and strong, it prevents
cells from bursting as they absorb water by osmosis.
The fibres of cell walls are laid down in different
directions to add strength.
Cell walls contain other substances making a tough
matrix. There is a "glue" between the cell
walls of adjacent cells.
Cell walls work with the vacuole to make a cell
turgid and to help support the plant.
