In this micrograph of a developing organelle, the trichocyst membrane is intact but does not bear the glycocalyx seen on the luminal side of the lysosomal membrane that lies nearby. The flocculant mat...

Fully formed trichocysts are moved from the cytosol to the cell surface along microtubules. In this image a bundle of microtubules arising from the proximal end of the basal body lies against the tric...

Electric shock causes massive trichocyst discharge and results in a large accumulation of HRP-labeled vesicles at the ectoplasmic/endoplasmic interface (at the level of the internal ends of the undisc...

Developing trichocyst containing a paracrystalline core surrounded by amorphous material and an autophagosome containing mitochodrion. TEM taken on 1/25/74 by R. Allen with Hitachi HU11A operating at ...

Freeze fracture image of the surface ridges at the anterior end of the cell where kineties to the right and left sides come together at an angle at the anterior suture tip. In this area are numerous p...

The infraciliary lattice in this quick-freeze deep-etched image consists of a meshwork of branching fibers composed of many subfibers. Basal bodies and trichocyst tips extend through the openings of t...

Food vacuole of Didinium. The food vacuole contains both exploded and unexploded trichocysts of Paramecium. Further details available at Wessenberg, H. and Antipa, G. 1968. Studies on Didinium nasutum...

Cortex and food vacuole of Didinium. The food vacuole contains unexploded trichocysts of Paramecium. Further details available at Wessenberg, H. and Antipa, G. 1968. Studies on Didinium nasutum. I. St...

Didinium ingests Paramecium. Also showing a few discharged trichocysts and metachronous waves of cilia in the two characteristic ciliary girdles of Didinium nasutum. This micrograph was taken in 1968 ...

A higher magnification view that shows the bilayer nature of the ciliary membrane, plasma membrane and the outer and inner (alveolar sac membranes of the alveoli. The 9-doublet + 2-singlet microtubula...
