The cell wall is a product of the cellular protoplasm and is primarily composed of which complex polysaccharide and related compounds?
Correct Answer
cellulose
Explanation
The plant cell wall is primarily composed of cellulose — a complex polysaccharide made of long chains of glucose units. Cellulose fibrils are laid down in a loose network to form the structural framework of the wall. Other compounds such as pectin and lignin are also present in varying amounts depending on the cell type.
