Answer 1

Такую бактерию можно увидить в электромикроскопе.

Answer 2

Can an Electron Microscope See a Bacterial Cell with a Diameter of 20μm?

Yes, an electron microscope can be used to see a bacterial cell with a diameter of 20μm. Electron microscopes have the ability to magnify objects to a much greater extent than light microscopes, making it possible to visualize very small structures such as bacterial cells.

Electron Microscope and Bacterial Cells: Electron microscopes use a beam of electrons to create an image of the specimen. This allows for much higher magnification and resolution compared to light microscopes, enabling the visualization of extremely small structures, including bacterial cells.

Visualization of Bacterial Cells: Bacterial cells are typically in the range of 0.5 to 5 micrometers in diameter, with some exceptions. Therefore, a bacterial cell with a diameter of 20μm would be well within the range of visualization using an electron microscope.
