Composition of Cell Wall
The composition of cell wall depends on the organisms of demand of the environment:
- Plants
- Cellulose: Provides structural support and rigidity.
- Hemicellulose: Contributes to strength and flexibility.
- Pectin: Helps hold cells together and regulates permeability.
- Lignin (in woody plants): Adds strength and waterproofing.
- Bacteria
- Peptidoglycan: Forms a mesh-like structure for support and protection.
- Lipopolysaccharides (in Gram-negative bacteria): Help anchor the cell wall and serve as antigens.
- Fungi
- Chitin: Provides strength and rigidity.
- Glucans and Mannans: Contribute to the structural framework.
- Algae
- Cellulose: Similar to plant cell walls.
- Sulfated polysaccharides (e.g., agar, carrageenan): Provide additional support and protection.
Cell Wall Diagram
The cell wall diagram illustrates its complex structure and diverse functions. Cell walls provide structural support, and protection, and regulate cell processes. The cell wall diagram class 9 and 11 is an important diagram that is often asked in the examinations. The cell wall is made up of primarily cellulose, polysaccharides, and proteins.
The labelled cell wall diagram in plant is given below:
