Prokaryotic cells

• How is DNA stored in a prokaryote?

  DNA is found as a single circular molecule in the cytoplasm and is not associated with histone proteins.
• What are the cell walls in prokaryotic cells made of?

  Prokaryotic cells have cell walls made of a glycoprotein called murein.
• Name and describe the three additional features that some bacteria can have.

  • Plasmids - Rings of DNA containing genes linked to survival such as antibiotic resistance.
  • Capsule - A layer surrounding their cell wall, which provides protection from other cells and helps bacteria agglutinate (stick together)
  • Flagellum - A long, thin filament that can spin to enable the bacteria to move.
• Complete the missing labels on the bacterium cell.
