Question
Outline how the structure of cellulose makes it suitable as a component of cell walls. [2]
▶️Answer/Explanation
Ans
a.chains of glucose/1-4 glycosidic linkages/covalent bonding between glucose ✔
b.beta glucose so alternating orientation of glucose units
OR
beta glucose forms straight chains ✔
c.forms microfibrils/long and thin/thin fibres/parallel bundles of cellulose molecules
OR
hydrogen bonding/cross linkage between cellulose molecules holds them together ✔
d.high tensile strength/rigid/doesn’t stretch so provides support/allows turgidity ✔
