NCBI Organism Classification
Vorticella convallaria
Biological Process
macronucleus organization
Cellular Component
macronucleus
Only the macronucleus contains nucleoli which is the site of ribosomal RNA synthesis and ribosome subunit assembly. This EM also contains the distal end of the food vacuole forming cytopharynx which c...

NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The new oral region in the opisthe starts to form as an unorganized field of new basal bodies develops at the equator of the cell surface. At first these do not resemble membranelles although some bas...

oral apparatus organization
Cellular Component
oral apparatus
The accessory microtubules at the proximal ends of the polykinetids, both in cross section and tangential section, are highlighted at higher magnification. This section shows one parasomal sac as well...

NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
phagosome acidification
Cellular Component
food vacuole
A nascent digestive vacuole with several acidosome-like vesicles docked at its cytosolic surface. The presence of the microtubules from the oral ribs signifies that this vacuole is still attached to t...

NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
digestive system process
Cellular Component
cytostome
Tetrahymena cells that are not forming a digestive vacuole often have a tube-like extension of the cytopharyngeal membrane attached to the deep fiber that extends several microns into the cytoplasm. T...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
microtubule cytoskeleton organization
Cellular Component
oral apparatus
The postoral fibers are also heavily labeled by anti-b-tubulin. The cell was lightly fixed, placed in metylcellulose and frozen in liquid nitrogen. Sections were produced at -100°C before thawing and...

NCBI Organism Classification
Halteria grandinella
Biological Process
microtubule cytoskeleton organization
Cellular Component
microtubule basal body
An image of the microtubular nemadesmata that extend deep into the cytosol from the membranelles of the perioral kinetids. Bridges link the plasma membrane to the alveoli. Parasomal sacs occur around ...

Biological Process
cytoplasm organization
Cellular Component
cytoplasm
Detail of cytopharyngeal vesicles. TEM taken on 3/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. Bar = 0.5µm. A print of the negative was scanned and processed in Photoshop. Th...

Nassula
Biological Process
contractile vacuole organization
Cellular Component
contractile vacuole
Contractile vacuole of Nassula sp. Parts of the single CV appear on two sides of the CV pore. Fields of spongiome abut the filled portions of the CV. TEM taken on 3/27/69 by R. Allen with Philips 300 ...
