• List common features of microbes

  • microscopic
  • made of organic compounds
  • everywhere in nature
  • single,multi and cluster
• common features of cells

  • cytoplasmic membrane
  • cell wall
  • cytoplasm
  • ribosome
  • genome
• all cells have

  • structure
  • metabolism
  • growth
  • evolution
• some cells have

  • differentiation
  • communication
  • movement
  • gene transfer
• 3 domains

  1. bacteria
  2. archea
  3. eukaryotic
• prokaryotes

  • no nucleus or organelles
  • circular chromosomes
  • bacteria or archea
• eukaryotes

  • have nucleus and organelles
  • linear chromosome
• molecular structure

  • genome
  • info macromolecules
  • eukaryties
  • prokaryotes
• RNA vs DNA


  RNA: ribonucelic acid, pentose sugar:ribose, nitrogenous bases and single stranded

  DNA: Deoxyribonucleic acid, pentose sugar: deoxyribose, nitrogenous base and double stranded
• where do microbes live
