OBJECTIVES:
1.1 The microscope in cell studies Learning outcomes
Candidates should be able to:
1 make temporary preparations of cellular material suitable for viewing with a light microscope
2 draw cells from microscope slides and photomicrographs
3 calculate magnifications of images and actual sizes of specimens from drawings, photomicrographs and electron micrographs (scanning and transmission)
4 use an eyepiece graticule and stage micrometer scale to make measurements and use the appropriate units, millimetre (mm),
micrometre (µm) and nanometre (nm)
5 define resolution and magnification and explain the differences between these terms, with reference to light microscopy and electron microscopy
