Rough endoplasmic reticulum

Newcomb, Eldon

Summary

• Transmission electron micrograph
• 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.
• The endoplasmic reticulum is a membrane system that pervades the cytoplasm of eukaryotic cells. The roughness of these views is due to ribososmes associated with the ER. Protein is produced at the ribosomes and this is a view of an area of a cell involved in protein production.
