Biological microscopes are available in a wide range of types due to the extraordinary range of specimen types.
For observation of individual cells, tissues, blood, micro-organisms then an upright microscope is most commonly used.  If the cells, micro-organisms or tissue are growing in culture then an inverted microscope can be used.
For non-transparent, larger specimens such a plant material or insects a stereo microscope is more suitable
