Transmission Electron Microscope
Transmits a beam of electrons through a very thinly sliced specimen.
Stage
The slide holding the specimen sits.
Organelle
One of several types of bodies with a specialized function that is suspended in the cytoplasm and found in eukaryotic cells
Nucleus
In an atom, the core of protons and neutrons; in a eukaryotic cell, the organelle that contains most of the DNA and directs most of the cell's activities.
Eukaryote
A cell that contains a nucleus and membrane-bound organelles.
