Detailed Characterization of the Cell Wall Structure and

cell wall  Find out what animal and plant cells are and learn what the function of the cell wall and the nucleus is in this KS3 Bitesize biology article  THE PLANT CELL WALL A Introduction = a tough coat of polysaccharides and proteins, which surrounds the plant cell external to the plasmalemma

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress It also allows The enzymatic degradation of the cell wall by either cellulasemacerozyme or endo-1,4-β-d-glucanasehemicellulasepectolyase partially exposed

While the chief component of prokaryotic cell walls is peptidoglycan, the major organic molecule in the plant cell wall is cellulose, a polysaccharide made up Bacteria: prokaryotic Very small No nucleus, no chloroplasts, no mitochondria Do have a cell wall Plant cells: eukaryotic Relatively large
