Question

Do archaebacteria have a cell wall?

Answer 1

Cell wall:

1. It is a specialised protective layer surrounding the outer side of the cell that provides structural and functional support.
2. It is made of various organic compounds like peptidoglycan, cellulose, pectin etc.

Archaebacteria:

1. These are primitive unicellular organisms that belong to prokaryotes.
2. Unlike bacteria, they evolved differently by having different cell wall constituents and slightly different processes in cellular replication.
3. Methanogens, thermophiles and halophiles belong to archaebacteria.
4. Archaebacteria has a well-defined cell wall that is not made of peptidoglycans like its eubacterial counterpart.
5. The cell wall is composed of various polysaccharides (polymers of sugar molecules like glucose) and proteins.
6. It provides rigidity and protection from the harsh outer environment.
