Prokaryotic Cell Structure

    Cards (7)

    • What is the function of the cell wall?
      • Physical barrier that excludes certain substances, made of murein
      • Protects against mechanical damage and osmotic lysis
    • Capsule
      • Protects bacterium from other cells
      • Helps groups of bacteria to stick together for further protection
    • Cell-surface membrane
      • Acts as a differentials permeable layer
      • Controls the entry and exit of chemicals
    • Circular DNA
      • Posseses the genetic information for the replication of bacterial cells
    • Plasmid
      • Possesses genes that may aid in the survival of bacteria in adverse conditions
      • e.g. produces enzymes that break down antibiotics
    • Flagellum
      Used for locomotion
    • Label the structures found in a prokaryotic cell.
      A) Flagellum
      B) Cell wall
      C) Circular DNA
