Describe the arrangement of glucose chains in cellulose.
About 60-70 cellulose molecules become cross-linked by hydrogen bonds to from bundles called microfibrils. These, will also form hydrogen bonds to form even bigger bundles called macrofibrils.

How does the arrangement of cellulose provide structural stability?
Macrofibrils run in all directions criss-crossing the wall for extra strength.
