Question

Unstained living cells can be best studied by

• A. Phase contrast microscope
• B. Electron microscope
• C. Fluorescent microscope
• D. Polarising microscope

The correct option is A Phase contrast microscope

Phase contrast microscopy is a type of microscopic technique which converts phase shifts in light passing through a transparent specimen to brightness changes in the image. This technique made possible to study living cells without staining.
