CAIE A Level Biology 9700 · Cell structure
A student calibrates an eyepiece graticule using a stage micrometer. The stage micrometer has divisions that are 0.01 mm apart. At the magnification being used, 40 eyepiece graticule divisions match 100 stage micrometer divisions. The student then uses the calibrated eyepiece graticule to measure the length of a plant cell.
Define the terms magnification and resolution as they apply to light microscopy.
4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.
Define means: Give the precise meaning of a term. Definitions are marked on exact wording. Learn them as written, including the key terms.
