Cell Wall Functions
Some of the cell wall functions are given below:
- Structural Support: Provides structural support and shape to the cell, helping it maintain its integrity and also helps in resisting mechanical stress.
- Protection: It acts as a barrier against physical damage, pathogens, and other external threats.
- Regulation of Cell Volume: Helps regulate the internal pressure and volume of the cell, preventing excessive swelling or bursting.
- Water Regulation: Helps in regulating water uptake and loss, maintaining optimal hydration levels for cellular processes.
- Support for Growth and Development: Provides a surface for cell expansion during growth and development, guiding the direction of cell expansion.
- Stress Response: Helps in the plant’s response to various environmental stresses such as drought, salinity, and extreme temperatures.
- Secondary Metabolite Production: Participates in the synthesis and deposition of secondary metabolites such as lignin in plant cell walls, which contributes to rigidity and defense.
- Selective Permeability: Controls the movement of molecules in and out of the cell, allowing essential nutrients to enter while keeping harmful substances out.
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:
