Cell wall

The cell wall is a feature of plant cells which causes them to be more rigid and uniform than animal cells. Made of insoluble cellulose fibres meshed in to a matrix of carbohydrates called pectates and hemicelluloses, it gives the plant strength and support.

The cell wall is generally permeable to anything entering the cell in solution unless impregnated with lignin? in wood or suberin? in cork tissue to produce wood.
