In addition to plates the plasma membrane contains IMPs on its P-fracture face in ring or parenthesis shape at sites of trichocyst secretion. A ring actually consists of two circles of IMPs and signif...

Quick-freeze deep-etch of granulo-fibrillar material at the crests of the ridges. This material is composed of thinner and shorter filaments that, like the striated bands, appear to bind to the membra...

CD3 mutant wheat (deficient in chlorophyll b) was germinated and grown for 6 days in the dark, greened at high light intensity in the presence of chloramphenicol for 4 days, thylakoids prepared, plun...

Freeze-fracture image of a chloroplast from barley (Hordeum vulgare) illustrating the characteristic size and distribution of particles on the EFu and EFs thylakoid membrane faces. The inset gives a h...

High magnification freeze-fracture image of a chloroplast from barley (Hordeum vulgare) illustrating the characteristic size and distribution of particles on the EFs and PFs faces of cleaved thylakoid...

Scanning electron micrograph of normal red blood cell (background, colored red) and red blood cell affected by sickle-cell anaemia (foreground, colored tan). Sickle-cell anemia is a blood disease that...

TEM images of reconstituted chromatin prepared from 12-mer tandem repeats of a strong nuclear positioning sequence and purified histones. Samples were fixed with glutaraldehyde, applied to carbon film...

Scanning electron microscope image of Strongylocentrotus drobachiensus [sea urchin] gastrula. This is a higher magnification image of CIL39765. The embryo was split open to reveal a nice cross-section...

Acidosomes originate from the biosynthetic pathway that includes the ER, the Golgi stack and the trans-Golgi network (TGN). Flattened vesicles from the TGN round up into spherical vesicles and bind to...

Colorized transmission electron micrograph of a platinum replica showing the cytoskeletal organization of stubby dendritic spines in extracted hippocampal neurons after 14 DIV. Unlabeled inset shows t...
