When trichocysts are triggered to discharge their contents the body of the trichocyst expands 8 or 9 times into a long needle like filament, however, the trichocyst tip does not change shape. The tric...

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...

The body of the trichocyst is composed of a core and a cortex which have slightly different electron diffracting properties, thus the cortex is darker since it scatters more electrons. An electron tra...

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...

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...

In a conventional freeze fracture view the membrane around the trichocyst tip is decorated with striations and IMPs. These decorations are found at the site where the trichocyst tip is associated with...

Tangential fractures through mature trichocysts. The planes in the paracrystalline stacks are exposed. The body is laced to the membrane but such associations must be severed when the trichocyst is di...

A high resolution image of portion of an isolated cilium exposing two rows of outer dynein arms arising from subfiber A of each doublet. The heavy chains of the dynein complex are linked to the microt...
