- A bacterial cell shows various parts and these parts have specific structure and functions.
- These parts are separated by a rigid cell wall some parts are on the internal side of the cell wall and some parts are on the external side of the cell wall.
- The parts present on the internal side of the cell wall are cell membrane, cytoplasm, nuclear region, reserve food material etc.
- The cellular parts present on external to the cell wall are flagella, capsule and pilia.
Structure and function of Cell wall
- The cell wall is the outer covering of bacterial cell in absence of capsule.
- This cell wall is rigid in nature which imparts a proper shape to bacteria.
- Cell wall encloses all internal parts of the cell.
- On the basis of typical structure, composition and Gram staining they are classified
A) Gram-positive bacteria.
