NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
cytoplasm organization
Cellular Component
peroxisome
A particularly large accumulation of peroxisomes each surrounded by a single membrane and containing a few short tubules in an otherwise granular matrix. TEM taken on 8/9/65 by R. Allen with RCA EMU3F...

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
Tetrahymena pyriformis
Biological Process
microtubule basal body duplication
Cellular Component
microtubule basal body
During division new basal bodies develop accessory fibers and begin to move apart to take up a position equidistant between the older complexes. The new kinetodesmal fiber seems to be associated with ...

Tetrahymena pyriformis
Biological Process
macronucleus organization
Cellular Component
macronucleus
A micrograph showing the polyploidal macronucleus of Tetrahymena containing many copies of the genome. Chromatin material is found as condensed electron opaque spots as well as in an uncondensed form...

Biological Process
oral apparatus organization
Cellular Component
oral apparatus
A cross section of the cell (ventral side up) through the buccal cavity showing basal bodies of the 3 membranelles (1, 2 and 3) lying along the indented dorsal wall. A short segment of the oral ribs s...

cell cortex
A micrograph of Tetrahymena showing a transverse ribbon starting from the anterior right side of the proximal end of a basal body (out of section plane) and crossing under the pellicle to end under th...

Tetrahymena pyriformis
Biological Process
phagocytosis
Cellular Component
phagocytic vesicle
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...

NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
digestive system process
Cellular Component
acidosome
The acidosome-like vesicle has at least 2 enclosing membranes or one membrane indented back on itself and an internal electron-opaque tongue-like droplet that is continuous with the enclosing membrane...

coated pit
High resolution micrograph of the cortex of Tetrahymena. One parasomal sac lies anterior to each basal body of the somatic ciliature. A parasomal sac is an indentation of the plasma membrane that pene...
