Conchophthirus was deciliated by calcium ion shock followed by shearing through a 22 gauge needle. This revealed the location of the deciliated basal bodies and the cell's surface architecture. In thi...

Quick-freeze deep-etch rotary-shadowed replica of an early endosome with two clathrin-coated evaginations. Presumably these coated pits contain receptors for cargo that will be pinched off from the ea...

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...

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...

Cells of the symbiotic prochlorophyte Prochloron didemni were separated from its ascidian partner, thylakoids isolated, treated to liberate chlorophyll-containing complexes, and negatively stained pre...

Didinium nasutum showing the two prominent girdles of cilia in full metachronous beat. If you look at higher magnification you will see the occasional short, blunt clavate cilia. These are known to no...

Morphology of the endoplasmic reticulum during a period of rapid cell differentiation. This micrograph shows two typical patterns of rough endoplasmic reticulum (RER) in developing liver from a one da...

High resolution image of the largest accumulation of endosomal vesicles and early endosomes is next to the buccal cavity area under the membranelles of the peniculi and quadrulus. Cilia of the penicul...

Two parasomal sacs that are oriented perpendicular to the basal bodies. The top parasomal sac has a clathrin cage around it's coated pit area. The P-face of the plasma membrane has some IMPs, particul...

Vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch preparation. Preendosomal ve...
