Prokaryotic Cells

• Structure of Plasmids: Plasmids are small loops of DNA that are separate from the main circular DNA molecule
• Function of Plasmids: Plasmids contain genes that can be passed between prokaryotes (e.g. genes for antibiotic resistance)
• Structure of a slime capsule: a final outer layer surrounding the cell.
• Function of a slime capsule:

  • It helps to protect bacteria from drying out
  • protects the bacteria from the host’s immune system
• Structure of flagellum: Flagellum (plural = flagella) are long, tail-like structure, made of microtubules.
• Function of flagellum: tail rotates like a propeller to move the cell.
• In prokaryotic cells what makes up the cell wall?

  Cell wall contains Murein
