NEET BIOLOGY

Detailed explanation-1: -This forms a rigid cell wall between cells, which help the organisms retain their shape. Much like in plant cells, water can be retained in the cells to create water pressure against the cell wall. This is known as turgor pressure and adds to the strength of each cell.

Detailed explanation-2: -Chitin and chitosan are two related polysaccharides that provide important structural stability to fungal cell walls. Often embedded deeply within the cell wall structure, these molecules anchor other components at the cell surface.

Detailed explanation-3: -Chitin is the main ingredient in the exoskeletons of arthropods and crustaceans and is also in the cell walls of fungi. That means everything from beetles, spiders, and butterflies to lobsters, crabs, and shrimp have some chitin in their protective armors.

Detailed explanation-4: -Chitin serves as a protective covering and mechanical support to soft-bodied organisms producing it. In insects and arthropods, chitin is a crucial component of their exoskeleton.

Detailed explanation-5: -Chitin is the most abundant renewable polymer in the oceans and is an important source of carbon and nitrogen for marine organisms. The process of chitin degradation is a key step in the cycling of nutrients in the oceans and chitinolytic bacteria play a significant role in this process.
