Question

a new multicellular organism has been discovered, and scientists want to study the organisms cell structures, including organelles. which microscope should they use?
scanning electron microscope
transmission electron microscope
compound light microscope
simple microscope

Explanation:

• Scanning electron microscope (SEM) provides a 3 - D view of the surface of objects. It is not ideal for internal organelle study as it mainly focuses on the surface.
• Transmission electron microscope (TEM) uses a beam of electrons that pass through the specimen. It can provide detailed images of internal cell structures including organelles.
• Compound light microscope has limited resolution and cannot clearly show most organelles.
• Simple microscope has even lower magnification and resolution compared to compound light microscope and is not suitable for organelle study.

Answer:

transmission electron microscope
