What type of microscope can be used to view the internal structure of a bacterium?

An electron microscope, specifically a transmission electron microscope (TEM), can be used to view the internal structure of a bacterium. This type of microscope uses a beam of electrons to create an image with much higher resolution than a light microscope, allowing researchers to see detailed internal structures of bacterial cells.


Is the cell membrane a backturuim?

No, the cell membrane is not a bacterium. The cell membrane is a biological structure that surrounds the cell and regulates the movement of molecules in and out of the cell. Bacteria are single-celled microorganisms that can have a cell membrane as part of their structure.


How do you know that Tetrahymena is not bacterium?

Tetrahymena is a single-celled protozoan, not a bacterium. It is classified as a eukaryotic organism, possessing complex organelles like a nucleus and mitochondria, which bacteria lack. Additionally, Tetrahymena's genetic makeup, reproduction method, and membrane structure differ significantly from bacteria.
