The two main types of electron microscopes are the transmission electron microscope (TEM) and the scanning electron microscope (SEM). Here, we briefly describe their similarities and differences. The difference between SEM and TEM The main difference between SEM and TEM is that SEM creates...
The first electron microscope was a transmission electron microscope (TEM) invented in Germany in 1931 by Max Knoll and Ernst Ruska. It was created as a way to magnify objects more than what light microscopes were capable of. If light microscopes could magnify up to 1000x or 2000x at best,...

1. How are solid tissue samples prepped for (a) LM, (b) TEM, (c) SEM? 2. What are the differences between LM and TEM tissue preparations(steps, dimensions, staining)? Explain the difference between dark skin and light skin. What is the difference between biopsy and histopatholo...
The methods for scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observation were previously described [20]. Semithin section observations of leaf and anther were previously described [21]. Image-Pro software was used to measure the size of epidermal cells at 1 K magni...
