  • 2 TYPES: Archaea and Bacteria
• Eukaryotes
  • Both Multicellular and Unicellular organisms
  • Nucleus and organelles enclosed in membranes
  • Some types are : Animal, Plant and Fungi
• Technologies for investigating cell structure and function
  • A range of technologies have been developed to expand the fields of cell biology and microbiology, allowing a deeper understanding of the prokaryotic and eukaryotic organisms which populate the earth.

• Light Microscopy
  • Passing of visible light through a sample with the use of lenses to magnify the image
  • Successfully image objects from 0.2 micrometers to 1 millimeter.
  • Common staining technique is Gram Staining: colours bacterial cell membranes either pink or purple to help identify cell
