Isolated chloroplast membranes of the unicellular photosynthetic alga Chlamydomonas reinhardtii were fixed, sectioned, and examined by transmission electron microscopy. Under the conditions used here,...

Transmission electron micrograph of a thin section of mouse intestine showing part of a cell with nucleus at left. The cytoplasm contains both membrane-associated polysomes (rough endoplasmic reticul...

Transmission electron micrograph of a thin section of a preparation of isolated and plastic embedded rat liver polyribosomes (also known as polysomes). Polysomes associated with the endoplasmic reticu...

Transmission electron micrograph of a thin section of a fibroblast from the ventricular myocardium of a rat showing a transverse view of rough endoplasmic reticulum (RER, sometimes termed granular end...

Transmission electron micrograph of a thin section of a capillary from the ventricular myocardium of the rat showing part of a reticulocyte (immature erythrocyte) in the lumen of the capillary. The re...

High resolution detail of cytopharyngeal vesicles. TEM taken on 3/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. The raw film was scanned with an Epson Perfection V750 Pro. This ...

Transmission electron micrograph of a section of Chinchilla epididimus showing the highly lobed nucleus seen in Principal sells of the epididymal epithelium characteristic of many mammals. Figure 111...

Transmission electron micrograph showing the extensive accumulation of darkly stained heterochromatin at the nuclear periphery typical of many differentiated cells. Heterochromatin is excluded from re...

Transmission electron micrographs of Opossum spermatogonia showing different regions within the nucleolus. One region is more lightly staining and fine textured, the other denser and more coarsely tex...

Transmission electron micrograph showing the highly compact nucleolus in the salamander hepatocyte. A finer textured central region is surrounded by a coarser region.
