Study Notes
Cell Walls and Envelopes
- The primary function of the cell wall in bacteria and plant cells is to provide structural support and protection.
Bacterial Cell Walls
- The major component of the bacterial cell wall is peptidoglycan.
- The Gram staining technique is used to categorize bacterial cell envelopes into Gram positive and Gram negative.
Gram Negative Bacteria
- The outermost layer of the cell envelope in Gram negative bacteria is the outer membrane.
Cell Envelope Structure
- The cell envelope or cell wall is observed in bacterial and plant cells.
- The cell envelope is located outside the cell membrane and provides structural support and protection to bacterial and plant cells.
Differences Between Gram Positive and Gram Negative Bacteria
- The major structural difference between Gram positive and Gram negative bacterial cell envelopes is the presence of a thick peptidoglycan layer in Gram positive bacteria and a thin peptidoglycan layer in Gram negative bacteria.
Unique Components of Gram Negative Bacteria
- Lipopolysaccharides are characteristic of Gram negative bacteria but not Gram positive bacteria.
- The additional component present in the cell envelope of Gram negative bacteria, but not in Gram positive bacteria, is lipopolysaccharides.
Shared Component of Bacterial and Plant Cells
- The cell wall is a common component of the cell envelope in both bacterial and plant cells.
