I want to know the answer to the following question:
What part of wood's cells are composed of cellulose and hemicellulose?
All the background I'm provided with is that "It consists of cells, and the cell walls are composed of micro-fibrils of cellulose (40% – 50%) and hemicellulose (15% – 25%) impregnated with lignin (15% – 30%).". Is that enough to answer the question?
Answer: yes
