Cellulose

• Cellulose is made up of beta-glucose.
• Cellulose has straight, unbranched chains that run parallel to each other, allowing hydtogen bonds to form cross-linkages between adjacent chains.
• The overall number og hydrogen bonds adds strength to cellulose.
• Structure of cellulose:

  
• The cellulose molecules are grouped together to form microfibrils, which are arranged in parallel groups called fibres.
• Cellulose is a major component in plant cell walls and provides rigidity to the plant cell.
• The cellulose cell wall also prevents the cell from bursting when water enters by osmosis.
• Cellulose stops water entering the cell by extering an inward pressure that stops any further influx of water.
• Plant cells are turgid and push against another.
• Cellulose's function is providing strength and rigidity.
• Cellulose is adapted by: cellulose molecules made up of beta-glucose and so form long, unbranched chains
• Cellulose is adapted by: cellulose molecular chains run parallel to each other and are cross linked by hydrogen bonds which add extra collective strength.
• Cellulose is adapted by: cellulose molecules are grouped to form microfibrils which in turn are grouped to form fibres, which provides more strength.
