B1- cell structure

• What are ribosomes responsible for.making


  Proteins
• Maximum resolution and magnification of a electron microscope


  1nm resolution and x500000 magnificatiom
• Standard form

  1 nanometre=

  1 mm=

  1 micrometre 


  1 nanometre= 1x10-9

  1 mm= 1x10-3

  1 micrometre = 1x10-6
• Magnification equation


  Magnification = magnified image /actual size of image
• 4 light microscope features are

  1-dont allow sub cellular structures to be seen

  2-allows cells to.be viewed as separate objects

  3-pass light through a specimen(can see a living thing)

  4-higher Resolution than human eye
