Euplotes sp.
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
A view of the cytopharynx and its nascent food vacuole forming region. The flattened pharyngeal vesicles that may contain monolayers or bilayers of lipids seem to be equivalent to the discoidal vesicl...

Biological Process
oral apparatus organization
Cellular Component
oral apparatus
A transverse section near the tip of the oral proboscis of Didinium. This micrograph shows the extrusive organelles of the mucocysts adjacent to the plasma membrane, the toxicysts in a circular ring a...

NCBI Organism Classification
Paramecium caudatum
Biological Process
oral apparatus organization
Cellular Component
endosome
Adapted with permission. Extensions of cytopharyngeal microtubular ribbons that pass into the endoplasm from the cytopharynx. Discoidal vesicles bind to one side only of these ribbons (the anterior si...

NCBI Organism Classification
Paramecium caudatum
Biological Process
phagocytosis
Cellular Component
oral apparatus
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...

oral apparatus
A transverse section near the mid region of the oral proboscis of Didinium. This micrograph shows the extrusive organelles of the mucocysts adjacent to the plasma membrane and the toxicysts. The pexic...

Vorticella convallaria
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
Cytopharynx with numerous folded membrane ribs subtended by five or so microtubules. These microtubules have arms that bind to other microtubules and to the membrane of the cytopharynx and to surround...

NCBI Organism Classification
Vorticella convallaria
Biological Process
response to food
Cellular Component
oral apparatus
Food vacuoles arise from the single membrane that lines the cytopharynx. Vesicles, similar to discoidal vesicles, attach to the cytopharyngeal microtubules (lamellar clumps) that arise from the dorsal...

Paramecium caudatum
Biological Process
digestion
Cellular Component
oral apparatus
This micrograph shows that the discoidal vesicles meet the cytopharyngeal membrane edge-on where they fuse. Besides the ribbon of 12 microtubules abutting the membrane there is a second small ribbon o...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
membrane docking
Cellular Component
early phagosome
Higher magnification of acidosomes docked at the nascent digestive vacuole membrane. The E-fracture face is relatively IMP free while the P-fracture face has many large IMPs as well as some sizable pi...
