Biology · Kingdom Protista

The cell wall of fungus like protista is composed of chitin.

Chitin is a structural polysaccharide found in the cell walls of fungi. It provides strength and rigidity, essential for maintaining the cell's structure and form. Chitin is also present in the exoskeletons of arthropods, such as insects and crustaceans, contributing to their protective outer layers.

Cellulose is a polysaccharide that is not found in the cell walls of fungi. Instead, it is a primary component of the cell walls of plants and some algae, providing structural support and rigidity.

Murein, also known as peptidoglycan, is found in the cell walls of bacteria, not fungi. It provides structural strength and shape to bacterial cell walls.

Lignin is a complex organic polymer found in the cell walls of plants, particularly in wood and bark. It provides rigidity and does not occur in fungal cell walls.
