Question

Phase-contrast microscope is used to see internal structures of cells in a natural state. This microscope enhances the contrast of transparent and colorless specimens, such as living cells, by converting phase differences in the light passing through the specimen into changes in light intensity. It does not require staining or fixation of the specimen, and thus allows observation of living cells. Electron microscope and fluorescence microscope are used to visualize structures that cannot be seen by light microscopy due to their small size or low contrast, while darkfield microscope is used to observe living, unstained cells in which more contrast is needed than brightfield microscopy can provide. Compound light microscope is a basic type of microscope that can be used to view stained and fixed specimens but lacks the resolution and magnification for viewing internal structures of cells in detail.
