Question

plant cell wall structure
middle lamella
pectin
primary cell wall
cross - linking glycan
plasma membrane
cellulose microfibrils
figure 1
what is the main material that bacteria cell walls are made from?
actin
amylose
peptidoglycan

Explanation:

To determine the main material of bacterial cell walls, we analyze each option:

• Actin is a protein involved in cell motility (e.g., in eukaryotic cells), not bacterial cell walls.
• Amylose is a polysaccharide (starch component), not a cell wall component.
• Peptidoglycan (or murein) is the key structural polymer in bacterial cell walls, providing rigidity and shape.

Answer:

C. peptidoglycan (assuming the options are labeled A: actin, B: amylose, C: peptidoglycan; adjust identifier if needed)
