The transmission electron micrographs included in this collection were all the work of Dr. Eldon Newcomb. Dr. Newcomb was a pioneer in the fixing and preparation of plant tissue for viewing with the transmission electron microscope. Dr. Newcomb generously allowed me to scan a sampling of his glass plates on a flat bed scanner. I do not have documentation about the source of the tissue scanned. However, each of these examples illustrates good generic views of plant cellular ultrastructure.
