bacteria cell

• bacteria cell

  A) Nucleoid

  B) mesosomes

  C) cytoplasm

  D) flagella

  E) pilus

  F) plasmids

  G) ribosomes

  H) plasma membrane

  I) cell wall

  J) capsule

  
• cell wall

  • fully permeable
  • there for support
  • made of peptidoglycan
  • gives the cell its shape
• plasma membrane

  partially permeable so controls what enters and leaves the cell
• pilus 


  act as a communication line
• mesosomes

  • may be involved in respiration
  • extension of the plasma membrane
  • guide duplicated bacterial chromosomes into two daughter cells during cell division
• ribosomes 


  where protein synthesis takes place, are smaller than in eukaryotes
• flagella 


  hairlike structures that provide movement for the cell
• cytoplasm 


  where chemical reactions take place
• nucleoid


  controls the activities of the cell
• capsule 


  stops the cell from drying out
• plasmids 


  small closed circles of DNA
• plasmids can move from one bacterium to another causing antibiotic resistance
