Structure of cellulose?

-Beta glucose arranged in a straight chain (each alternative beta glucose is rotated 180 degrees)=cellulose straight chain.

-many cellulose chains are cross linked by hydrogen bonds to form microfibrils.

-many microfibrils are cross linked to form marcrofibrils.

-forms structure of cell wall.

-strong material (prevents plant from bursting or shrinking).
