CIL:36219
NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
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
Vorticella convallaria
Biological Process
cortical cytoskeleton organization
Cellular Component
pellicle
Fibers that splay out from a mid piece pass to the pellicle. TEM taken on 4/5/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 10,250X. Bar = 1µm. Published and adapted with permission from ...

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...

NCBI Organism Classification
Vorticella convallaria
Biological Process
calcium ion transport
Cellular Component
microfibril
The spasmoneme contains membranous tubules that are known to store calcium (see Favard, P. and N. Carasso, J. Microscopie 3:671-696, 1964) and to be modified ER. The alveoli only partially surround th...

cell
11 micrographs are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 3 food vacuoles (of a total of about 15 in the cell...

NCBI Organism Classification
Vorticella convallaria
Biological Process
cortical cytoskeleton organization
Cellular Component
cell cortex
Mitochondria of Vorticella convallaria like other ciliates, have tubular cristae arising from their inner membranes. However, they also have a bundle of filaments (DNA?) that extend through the center...

NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
microtubule basal body duplication
Cellular Component
microtubule basal body
Up to three basal bodies have been seen in various stages of development near a mature basal body/cilium complex. In this micrograph 2 new basal bodies are present next to 2 cilia and 3 are forming ne...

NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
cytoplasm organization
Cellular Component
lysosome
The acidosome-like vesicle has a bull’s eye appearance with the invagination appearing in the middle of the vesicle. Other vesicles contain multiple layers resembling multilipid layers. Two vesicles...
CIL:36712
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
microtubule cytoskeleton organization
Cellular Component
microtubule associated complex
The cytopharyngeal ribbons of microtubules tend to curve into a “C” shape away from the cytopharynx but they still remain connected as a ribbon and are heavily labeled by immunogold when exposed t...
