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...

This group represents a serial series of sections. At the level of this section, a little deeper in the cell the spongiome of the CV is more pronounced. Oral membranelles in the buccal cavity are indi...

of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Scanning electron micrograph of the epidermal surface of the flatfish sole Parophrys detulus shows a labyrinth of surface ridges. Image from Fahrenbach,...

The contractile vacuole pore is supported on its cytosolic side by a coil of microtubules and other microtubules extend from the pore to the CV membrane. The plasma membrane and CV membrane cover the ...

Freeze fracture of the plasma membrane and outer alveolar membrane of the pellicle of V. microstoma. The surface of Vorticella is encircled by rings which follow the septa of underlying alveoli. In th...

In quick-freeze deep-etch preparations the plasma membrane can be seen to contain plaques or plates of intramembrane particles (IMPs) that are regularly aligned in rows with a center-to-center spacing...

High resolution image on the multiple membrane systems at the cortex of ciliates. Thickened alveolar densities partially coat the alveolar membrane within the alveoli which underlie the plasma membran...

This freeze fracture view of the pellicle of V. microstoma near the aboral end of the zooid shows the region where the width of each circumferential alveolus is narrower and thus the strings of fractu...
