What Is Tem In Biology

What Is Tem In Biology. Ultrastructure the tem can be used to visualise the complexity of cells and show cellular structures. Advanced tem techniques may require instruments capable of an av between 200 kv and 3 mv, which represent a resolution 100,000 to 3 million times smaller than light microscope resolution.
