Which microscopy technique is most commonly used to study the ultrastructure of internal cellular organelles (e.g., mitochondria, ER)?
Show answer and explanation
Correct answer: Transmission electron microscopy (TEM)
Transmission electron microscopy (TEM) uses electrons passed through ultrathin sections and heavy-metal staining to visualize internal cell architecture at high resolution, enabling clear visualization of organelles such as mitochondria, nucleus, and Golgi.
