SUMMARY
In phase contrast microscopy, when the refractive index of the medium matches that of the cell, visibility is limited to specific cellular structures such as membranes, vesicles, the nucleus, pigment granules, and the brush border. The discussion highlights that the refractive index of a cell is not uniform, which is crucial for the effectiveness of phase contrast and differential interference contrast (DIC) microscopy. The assertion that no visibility occurs under these conditions is incorrect, as certain cellular components remain discernible.
