CIL:36663
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
macronucleus organization
Cellular Component
macronucleus
In one experiment in which electric shock was applied to Paramecium cells to trigger trichocyst discharge the macronucleus in one cell was observed to undergo morphological changes of two types. First...

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...

NCBI Organism Classification
Paramecium caudatum
Biological Process
micronucleus organization
Cellular Component
micronucleus
The micronucleus of Paramecium caudatum is distinctive from other closely related Paramecium such as P. multimicronucleatum and P. tetraurela. P. caudatum has only one micronucleus of a type in which ...

Paramecium caudatum
Biological Process
plasma membrane organization
Cellular Component
cell cortex
A grazing section through the cell’s surface shows segments of six rows of cilia running across the figure sectioned superfically at the top and deeper into the cell as one progresses down the figur...

NCBI Organism Classification
Paramecium caudatum
Biological Process
ciliary or flagellar motility
Cellular Component
cilium
Cross section of a cilium showing the 9 + 2 axoneme. Two dynein arms, inner and outer, of heterogeneous appearance arise from the complete microtubule of each doublet. Spokes extend from the doublets ...

NCBI Organism Classification
Paramecium caudatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The highest concentration of parasomal sacs is found in the oral region associated with the three ciliary membranelles, called in Paramecium, the ventral amd dorsal peniculi and the quadrulus. This mi...
CIL:36776
NCBI Organism Classification
Paramecium caudatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
Posterior end of the buccal cavity with a nascent phagosome attached to the cytopharynx. The ribbed wall has ended and the cytopharynx is greatly reduced. The quadrulus goes to the end of the buccal c...
CIL:38686
NCBI Organism Classification
Paramecium tetraurelia
Biological Process
microtubule cytoskeleton organization
Cellular Component
cell cortex
High resolution image of microtubules that sometimes extend deep into the cytosol from the basal bodies. They serve to guide the trichocysts to their docking sites at the plasma membrane (see Plattner...
CIL:38689
NCBI Organism Classification
Paramecium tetraurelia
Biological Process
contractile vacuole organization
Cellular Component
contractile vacuole
A high resolution view of the radial arm of the Contractile Vacuole Complex or CVC each contain a collecting canal enclosed by a microtubular ribbon split lengthwise into several smaller ribbons, a me...
CIL:39113
NCBI Organism Classification
Euplotes sp.
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The AZM enters the oral cavity of Euplotes where it occupies the right side of the buccal cavity while cytopharyngeal lamellae composed of microtubules arise from the left wall of the cavity. Large ve...
