Final answer:
Chitin is a key component of fungal cell walls, providing structural strength, which is essential for the protection of fungal cells. The answer to whether chitin is part of the fungal cell wall is A) True.
Step-by-step explanation:
In fungi, chitin provides structural strength to the cell walls, much like it provides durability to the exoskeletons of arthropods, such as insects and crustaceans. This complex polysaccharide, a long-chain polymer of N-acetyl-D-glucosamine, is crucial for protecting fungal cells from desiccation and predators. In contrast to fungal cell walls, which contain chitin, plant cell walls are made up of cellulose. The presence of chitin is one of the unique features that distinguishes fungal cells from those of other eukaryotic organisms.
