Origin of ultrastructure:
The fine, detailed structure of a biological specimen that can only be observed by electron microscopy
Ultrastructure is the detailed structure of a biological specimen, such as a cell, tissue, or organ, that can be observed by electron microscopy. It refers in general to the study of cellular structures that are too small to be seen with an optical microscope. These cellular structures are known as organelles and allow the cell to function properly within its specified environment. The structures of an animal cell are the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, lysosomes, ribosomes, and centrioles. The plant cell has all of the above and the addition of a cell wall, and chloroplasts which aid photosynthesis. Ultrastructure, along with molecular phylogeny, has often been a reliable way of classifying organisms.
