Fungi are saprophytes in nature. They tend to live on dead organisms. They do not possess chlorophyll. Their cell wall is made up of chitin. The cell wall of fungi is a dynamic structure that protects the cell from environmental stress and prevents from various effects that are caused due to changes in osmotic pressure. Biosynthesis is a unique feature of the fungal cell wall. The cell wall of fungi is rigid and composed of complex polysaccharides such as chitin, glucans and glycoproteins. The cell wall provides the structural framework, rigidity and protects from desiccation and predation.
