Study Notes
Cell Wall Overview
- Cell walls are found in fungi, bacteria, and plants, providing structure and protection.
- Located outside the cell membrane, the cell wall forms a boundary that supports and shapes the cell.
Composition of Cell Walls
- Composed primarily of cellulose and peptidoglycan, which are types of carbohydrates.
- Cellulose is a fundamental component in plant cell walls, contributing to rigidity and strength.
Structure of Cell Walls
- Consist of two main layers: primary wall (flexible, allows for growth) and secondary wall (thicker, provides additional strength).
- The structural composition supports various functions and adaptations among different organisms.
Characteristics of Cell Walls
- Described as thick, stiff, and rigid, contributing to overall cellular integrity.
- The rigidity of cell walls helps maintain shape and prevents deformation under various environmental pressures.
Functions of Cell Walls
- Serves as a skeleton for plants, providing mechanical support and resistance to external forces.
- Protects the internal contents of the cell from physical damage and pathogens.
- Regulates cell growth by controlling the rate of expansion during cell division and development.
