Which instrument is typically used to observe cells?

The microscope is the most suitable instrument for observing cells because it is specifically designed to magnify small objects that are often not visible to the naked eye. Cells are typically very small, measuring in micrometers, and require high magnification and resolution to be seen clearly. Microscopes can provide different levels of magnification and various techniques, such as light or electron microscopy, allowing scientists to see cell structures in detail, including organelles like the nucleus, mitochondria, and cell membrane.

Other instruments, such as a stethoscope, are intended for listening to internal body sounds and are not capable of visual observation. A magnifying glass can provide some magnification, but it is limited in its ability to resolve fine details, making it less effective for observing cells than a microscope. A telescope is designed for viewing distant objects, such as stars and planets, and is not suitable for examining small biological specimens like cells. Thus, the microscope stands out as the primary tool for cell observation in biological studies.
