Is flagellum visible with a light microscope?

Yes, a flagellum is generally visible with a light microscope, but its visibility can depend on the type and thickness of the flagellum, as well as the staining techniques used. In many cases, flagella are thin and may require specific staining methods or higher magnifications to be clearly observed. While light microscopy can provide a basic view, more detailed examination often requires electron microscopy to visualize the fine structure of flagella.
