(b) For practical assessment, candidates may be required to operate a light microscope, mount slides and use an eyepiece graticule and a stage micrometer.
You should refer to your notes, 'Consolidated Notes on Microscopy'.
The microscope enables us to view beautiful biological specimens that are not visible to the naked eye, and it is an instrument that should be handled with care. It is important to be familiar with the various parts of the microscope and know how to use it correctly to view a specimen clearly.
