Molecular Expressions Microscopy Primer: Introduction to Microscopy. Introduction to Optical Microscopy,Digital Imaging, and Photomicrography This treatise on optical microscopy is divided into several sections that are available through the links displayed immediately to the left (in the darker navigational boxes) and below. In order to print the entire microscopy primer as a paper document, you must download each link independently, send the file to your printer, and put the results together.
In the Bibliography, we have included links to other works on optical microscopy and our section on Web Resources contains links to other microscopy sites on the Internet. This material is targeted for educational purposes only, and is not available to be posted on remote websites (either commercial or educational) or distributed in any electronic format. Frequently Asked Questions - Mortimer Abramowitz, senior microscopist at Olympus America Inc., answers the 50 most commonly asked questions about microscopy and photomicrography.
Questions or comments? DLC-ME | The Microbe Zoo. Small Things Considered. By Daniel P. Haeusser How did Eukaryotes Evolve from Prokaryotes? Figure 1. The mysterious root of the eukaryotic origin. One of the most exciting and enduring obscurities of biology lies in the early stages of the evolution of “our” eukaryotic cells (Figure 1). Even murkier is the question regarding the origin of the nucleus (Figure 2). Unlike the clear bacterial origin of the mitochondria and chloroplast, it turns out that no single existing model has received broad acceptance to explain the existence of the nucleus. Figure 2. Not only are details on the evolution of these eukaryotic innovations (nucleus and mitochondria or chloroplast) shrouded in mystery, but just as unclear is the temporal relation between their developments. A recent online article by Ed Yong for Nautilus Magazine gives a comprehensive summary of one of the prevailing hypotheses proposed to answer that question.
