Detail of the filamentous reticulum along the left side of the cytopharynx from which cytopharyngeal ribbons arise next to its nodes. Quadrulus associated ribbons lie between the filamentous reticulum...

At the cytopharynx the acidosomes come in contact with the carrier vesicles that are derived from early endosomes. These carrier vesicles bind to the microtubular ribbons as do the acidosomes. The car...

The collapsed cytopharyngeal membrane extends from the open cytopharynx into the cytosol. This membrane is associated with many docked acidosomes, vesicles that contain V-type proton translocating ATP...

Carrier vesicles are around 100nm in diameter. They can carpet the cytopharyngeal ribbons with a layer of vesicles, several vesicles wide, as shown in this micrograph. As seen here the ribbons come to...

One segment of the assembly line used for phagosome membrane growth in P. caudatum. Cytopharyngeal ribbons bring discoidal vesicles to the left lip of the cytopharynx where the vesicles bind and then ...

Accumulations of acidosome-like vesicles are sometimes found (in this case in a predividing cell) and in this micrograph provide further evidence for invaginations of the outer membranes. It appears t...

Phagocyte and budded yeast. Amoebae (D. discoideum) were plated with yeast (S. cerevisiae) in a glass bottom chamber and viewed by confocal microscopy. Fluorescence is superimposed on grey scale brigh...
