Ultrastructure
Detail hidden to optical microscopes / From Wikipedia, the free encyclopedia
Ultrastructure (or ultra-structure) is the architecture of cells and biomaterials that is visible at higher magnifications than found on a standard optical light microscope. This traditionally meant the resolution and magnification range of a conventional transmission electron microscope (TEM) when viewing biological specimens such as cells, tissue, or organs. Ultrastructure can also be viewed with scanning electron microscopy and super-resolution microscopy, although TEM is a standard histology technique for viewing ultrastructure. Such cellular structures as organelles, which allow the cell to function properly within its specified environment, can be examined at the ultrastructural level.

Ultrastructure, along with molecular phylogeny, is a reliable phylogenetic way of classifying organisms.[1] Features of ultrastructure are used industrially to control material properties and promote biocompatibility.
