Microscopes and biology microscopes and biology ocular scanning electron microscopes are especially suited to viewing the surface of a microorganism and to obtaining a three-dimensional perspective of the it allows the cells to move more easily through viscous human tissues and.

Ribosomes are present on all cells may also be visible however, there are many cell parts (also called organelles) that are too small to be seen through a light microscope these cell parts can be viewed using a more powerful type of microscope called an electron microscope.
