CIL:36790
NCBI Organism Classification
Paramecium caudatum
Biological Process
digestion
Cellular Component
cytoproct
The cytoproct is the cell’s defecation site where spent digestive vacuoles fuse with the plasma membrane. In this cell the cytoproct is closed and forms a ridge along the posterior suture on the ven...

NCBI Organism Classification
Paramecium caudatum
Biological Process
cortical cytoskeleton organization
Cellular Component
cortical microtubule cytoskeleton
Kinetodesmal fibers arise from the proximal ends of the basal bodies and curve upward and to the cell’s right of the kinety. Together with kds arising from more posterior basal bodies they form a st...

NCBI Organism Classification
Paramecium caudatum
Biological Process
cortical cytoskeleton organization
Cellular Component
cell cortex
Stacks of 4 or 5 kinetodesmal fibers occupy the longitudinal ridges in a cross-sectioned cell. The kds lie along the right side of each ridge (cell’s left side), and as the kds are tapered, the smal...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
nuclear division
Cellular Component
micronucleus
Except that the nuclear envelope remains intact, micronuclear mitosis occurs in a normal way passing through the four stages of prophase, metaphase, anaphase and telophase. In this example a micronucl...
CIL:36657
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
pronuclear migration
Cellular Component
pronucleus
During self conjugation two cells from a 6-day old culture come together, bridges are formed between them and haploid products of meiotic division of their micronuclei are exchanged between the mating...
CIL:36631
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
mitochondrial proton-transporting ATP synthase complex assembly
Cellular Component
mitochondrion
Occasionally mitochondria of Paramecium become filled with cristae that display a wavy or helical pattern. In thin sections these cristae are viewed as curved arcs as well as cross sectioned rows in d...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
endocytic vesicle lumen
In some cells exposed to horseradish peroxidase (HRP) for 30 sec and then immediately fixed some HRP has already entered the cell by endocytosis and has been removed from the early endosomes in carrie...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
food vacuole
In order to study all stages of DVs in the same cell we used a protocol of sequentially exposing cells to different sizes of latex beads interspersed with washes: for example, 3 minutes in 0.1µm bead...

NCBI Organism Classification
Vorticella convallaria
Biological Process
digestive system process
Cellular Component
cell
11 micrographs of views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 4 food vacuoles; 3 segments of the macronucleus; peri...
CIL:39460
NCBI Organism Classification
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...
