structure and function

• cell wall structure

  prokaryotic cells are surrounded by a cell wall made of peptidoglycan
• capsule function

  slippery layer outside the cell wall of some species of bacteria
• ribosomes structure

  smaller than ribosomes found in eukaryotic cells. consist of two sub-units and they are not surrounded by a membrane
• nucleoid (nucleus like) structure 


  irregularly shaped region that holds nuclear material without nuclear membrane and where genetic material localised
• plasmid structure


  small circular loops of dna
• cell wall function

  protects and supports each cell
• capsule function

  protects the cell and prevents dessication
• ribosomes function

  protein synthesis occurs at ribosomes
• nucleoid function


  region where genetic information can be found and controls cellular activity
• plasmid function

  carry genes that may benefit the survival of the organism
