1. Provides structural support and shape to the cell 2. Protects the cell from mechanical damage and pathogens 3. Regulates the movement of substances in and out of the cell 4. Helps maintain the cell's turgor pressure 5. Plays a role in cell-to-cell communication and signaling 6. Provides a barrier against desiccation (drying out) in plant cells 7. Contributes to the overall rigidity and strength of the cell.

Functions of the Cell Wall:
1. Structural Support and Protection: - Provides structural rigidity to the cell, preventing it from collapsing under osmotic pressure. - Protects the cell from physical and chemical damage.
2. Cell Shape Maintenance: - Dictates the shape of the cell, determining whether it is rod-shaped, spherical, or irregular.
3. Cell Division: - Forms the division septum during cell division, separating the two daughter cells.
4. Nutrient Absorption: - Bacteria possess a cell wall that facilitates the absorption of nutrients from the environment.
5. Cell-to-Cell Interaction: - In bacteria, the cell wall contains attachment sites for fimbriae and pili, which are important for cell adhesion and communication.
6. Antibiotic Resistance: - The cell wall serves as a barrier against antibiotics in bacteria, contributing to antibiotic resistance.
7. Pathogenicity: - In pathogenic organisms, the cell wall is involved in the attachment and colonization of host tissues.
8. Selective Permeability: - Cell walls regulate the passage of molecules into and out of the cell, maintaining the cell's internal environment.
9. Cell Wall Antibiotics: - Cell wall antibiotics target the synthesis or integrity of the cell wall, making them effective against bacteria.
10. Plant Cell Differentiation: - Cell walls in plants play a role in differentiation, forming specialized structures such as xylem and phloem.
