Study Notes
Cell Walls
- The primary function of a cell wall is to provide structural support, maintenance of cell shape, and protection against external forces.
Organisms with Cell Walls
- Cell walls are commonly found in bacteria, archaea, fungi, and plant cells.
Role in Osmotic Pressure and Mechanical Stress
- The cell wall helps the cell withstand osmotic pressure and mechanical stress by providing rigidity and maintaining the cell's internal environment.
Cells Without Cell Walls
- Cell walls are absent in animal cells and some protists, such as protozoa.
