BRAINCAKECellulose Cell Wall
The cell wall encloses all plant cells. Cellulose is a polymer of beta-glucose. Long molecules of cellulose are bound together to form strong fibres. The fibres form a mat glued together by object and hemicellulases.
The cell wall is freely permeable to water and small molecules.
