A condensation reaction joins many beta-glucose monomers together, to for a chain of beta-glucose. Then beta-glucose chain joins together by hydrogen bonds to form microfibrils. Then microfibrils join together to form fibers which makes up the cellulose in plant cell walls. Have I described this correctly? Thanks! =)

Erm, if you are doing AQA it would be a good idea to state that a glycosidic bond is formed and relate structure to function. Here's an example:

'Many b-glucose join together by glycosidic bond in a condensation reaction to form an unbranched chain. The B-glucose.is inverted successive to form a straight chain. The straight chain prevents hydrolysis to occur as the cross linkage prevent access of water molecules. The hydrogen bond between them form micro fibrils, which provide structural support (gives strength and rigidity to plant cell walls). This prevents the cells bursting when water enters by osmosis so they become turgid'

Pretty much mention the fact that b-glucose is rotated/inverted to form unbranched straight chains, glycosidic bond is formed, and related structure to function.

Sorry for long answer (so hard to write it on my phone -.-)
