Every other b-Glucose molecule is rotates 180 degrees + H bonds between rotated b-Glucose gives strength and prevents spiralling
1 of 8
How does Cellulose arrange itself?
several hundred cellulose chains arrange themselves into fibrils with H bonding to add strength and stability. (Microfibrils and Microfibrils)
2 of 8
Why is Cellulose important for the structure of the cell wall?
Micro and microfibrils have high tensile strength= glycosidic and H bonds. Microfibrils run in all directions= criss crossing for extra strength. Difficult to digest cellulose due to G bonds between glucose molecules.

Why is Cellulose important for the function of the cell wall?
Cellulose is strong to help support the plants and keep cells turgid. Space between microfibrils for water and ions= fully permeable membrane.

What are bacterial cell walls made from?
Peptidoglycan
5 of 8
What are exoskeletons made from?
Chitin
6 of 8
What would happen to the cell wall if Cellulose was made from a-Glucose
As the OH group would not rotate, H bonds would not form between chains= Lower tensile strength
7 of 8
How and why should the plant cell wall be waterproofed in the Xylem vessel?
Its waterproofed by the Lignin vessel because the xylem distributes water around the plant and its important the water does not diffuse out of the column.
