Answer

Exceptions to Prokaryotic Cell Wall

1. Mycoplasma
- Mycoplasma is a genus of bacteria that lack a cell wall.
- Instead of a cell wall, they have a unique cytoplasmic membrane that contains sterols to provide structural support.
- Due to the absence of a cell wall, Mycoplasma species have a pleomorphic shape and are able to take on various forms.

Importance of Cell Wall
- The cell wall is a rigid structure that surrounds the cell membrane in most prokaryotic cells.
- It provides structural support and protection to the cell, helping maintain its shape and prevent lysis.
- The cell wall also plays a role in cell division, as it helps in the separation of daughter cells.

Role of Cell Wall in Prokaryotic Cells
- In prokaryotic cells, the cell wall is composed of peptidoglycan, a polymer that consists of sugars and amino acids.
- The cell wall helps bacteria resist osmotic pressure changes and protects them from environmental stresses.
- It also serves as a barrier against harmful substances and contributes to the virulence of pathogenic bacteria.

Conclusion
- While most prokaryotic cells have a cell wall, Mycoplasma is an exception to this rule.
- The absence of a cell wall in Mycoplasma is compensated by other structural adaptations, highlighting the diversity and adaptability of prokaryotic organisms.
