Quick-freeze deep-etch image of a cytosolic region where trichocysts are developing. Vesicles, even small ones, contain contents that are compacting into paracrystalline form. These vesicles seem to h...

Mouse skeletal muscle. This image depicts a transmission electron micrograph of 1 month old mouse skeletal muscle tissue from the EDL muscle. Note the highly ordered organization of the contractile ap...

A fracture of an apparently fully formed trichocyst showing that the body of paracrystalline material fills the organelles lumen and is bound to the membrane by a loose array of threads. The membrane,...

The tip of the trichocyst does not expand but remains nail shaped and remains bound to the elongated shaft. TEM taken on 6/7/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0....

QF-DE of a crystal whose P-fracture face shows many IMPs similar to the P-face of an acidosome lying nearby and trichocyst as well as trichocyst precursor vesicles. TEM taken by C. Schroeder on 6/3/8...

The thylakoids of the vegetative cells of the filamentous cyanobacteria, Oscillatoria tenuis, are capable of oxygen-evolving photosynthesis. Freeze-fracture replicas of the vegetative cells revealed ...

Larger vesicles contain paracrystalline cores that are associated at one end with the trichocyst membrane. This may mean that there is a site on the membrane that promotes paracrystalline formation or...

Released from the cell the trichocyst lengthens and its internal meshwork opens up into an elongated needle. TEM taken on 6/7/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 24,880X. Bar = 0...
