Cellulose

• what is cellulose

  • a polysaccharide made up of b-glucose monomers
• why is cellulose important in plants

  • acts as a structural carbohydrate
  • important in plant cell walls
• how does cellulose help give the plant rigidity

  • as cellulose cell wall is inelastic
  • has high tensile strength to prevent plant cells from bursting
• describe the cellulose structure

  • b-glucose monomers joined together by glycosidic bonds
  • w each adjacent b-glucose molecule ROTATED 180°
  • forms straight chains
  • hydrogen bonds form between the straight chains
• what are many straight chains joined together by many hydrogen bonds form

  strong microfibril
• what do many microfibrils form

  a strong cellulose bundle
• describe the function of cellulose

  structure in plant cell walls
• describe the chain type in cellulose

  straight
• describe the monomer type in cellulose

  b-glucose
• describe the properties of cellulose

  • strong
  • high tensile strength
  • permeable
• describe type of glycosidic bond cellulose has
