The cell wall of a fungus is made mainly of
Correct answer: C. chitin
- A. cellulose
- B. peptidoglycan
- C. chitin
- D. lignin
Explanation
Fungal walls are built from chitin, the same nitrogen containing polysaccharide found in the exoskeleton of insects, which is one reason fungi are placed in their own kingdom rather than with plants. Plant walls are cellulose and bacterial walls are peptidoglycan. Lignin is an additional strengthening material deposited in the walls of woody plant tissue.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.
