Structure and Ultrastructure of Microorganisms: An Introduction to a Comparative Substructural Anatomy of Cellular Organization presents the structure or principle of operation of the electron microscope. This book provides an introduction to the submicroscopical anatomy of the cell in ultrathin sections of tissues or of single-cell organisms. Organized into 30 chapters, this book begins with an overview of the structures discovered by the use of an optical tool for observation. This text then examines the anatomical principle to the nucleus. Other chapters consider the structural organization of chromatin as revealed in electron micrographs of thin sections through cells in different stages of division. This book discusses as well the macronuclei of the ciliates, which plays a significant part in the reproductive mechanism. The final chapter deals with the micromolecular organization of bacterial flagella. This book is a valuable resource for scientists, biologist, physicists, protozoologists, cytologists, biochemists, biophysicists, and research workers.
