Peptidoglycan
C
Chitin
D
Cellulose
Verified step by step guidance
1
Understand that the cell wall is a structural layer surrounding some types of cells, just outside the cell membrane.
Recognize that different organisms have different primary components in their cell walls. For example, plants have cellulose, bacteria have peptidoglycan, and fungi have chitin.
Recall that chitin is a long-chain polymer of a N-acetylglucosamine, a derivative of glucose, and is a key component in the cell walls of fungi.
Differentiate between the options given: Lignin is primarily found in the cell walls of plants, providing rigidity and does not occur in fungi. Peptidoglycan is found in bacterial cell walls, not in fungi.
Conclude that the primary component of the cell wall in fungi is chitin, which provides structural support and protection.
