- Cellulose
- plant cell walls
- tough, insoluble, fibrous
- straight chains of beta-glucose (joined by condensation reactions)
- 60-70 cellulose chains= microfibrils, then macrofibrils
- all embedded in pectin= cell walls
- macrofibrils criss-cross for extra strength
- structure helps with function
- macs/mics =high tensile strength
- because of glycosidic and hydrogen bonds
- difficult to digest because glycosidic bonds
- each cell needs strength for support because no skeleton
- cell walls fully permeable
- walls= high tensile strength so when turgid no bursting
- turgid cells support each other
- macs/mics =high tensile strength
