NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
contractile vacuole organization
Cellular Component
contractile vacuole
Quick-freeze deep-etch image of a fracture through the radial canal of the contractile vacuole. This technique presents a picture of a confusing array of non-etchable material surrounding a collecting...

Paramecium multimicronucleatum
Biological Process
plasma membrane organization
Cellular Component
plasma membrane
In quick-freeze deep-etch preparations in which cells are slam frozen the pellicle and the plasma membrane tends to be flattened. The double rings are present but only the outer ring of IMPs stand out...

plasma membrane organization
Cellular Component
plasma membrane
In a conventional freeze fracture view the membrane around the trichocyst tip is decorated with striations and IMPs. These decorations are found at the site where the trichocyst tip is associated with...

pellicle
Freeze fracture image of the surface ridges at the anterior end of the cell where kineties to the right and left sides come together at an angle at the anterior suture tip. In this area are numerous p...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
food vacuole
Conventional freeze-fractured images of DV-III membrane also suggests a transformation from a membrane with a smooth E-fracture face to one with characteristic large IMPs on its E-fracture face. The D...

Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
food vacuole
Quick-freeze deep-etch image of a DV-III containing paracrystalline sheets in its lumen. The sheets have parallel rows of subunits spaced at 20nm center-to-center but the chemical nature of the sheets...

plasma membrane organization
Cellular Component
plasma membrane
In this image a portion of the true surface of the plasma membrane is exposed where the culture medium has been etched away. The IMPs of the plates can also be viewed less distinctly on the true surfa...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
mitochondrion organization
Cellular Component
mitochondrial membrane
Isolated mitochondria that have been quick-frozen, fractured and deep-etched show some space between the inner and outer membranes. Arcs of tubules, where they are tangentially fractured, show the hel...

Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
The ingestion of Paramecium by Didinium. This micrograph also clearly shows the five short rows of clavate cilia (ciliary stubs without central microtubules) that reside just below the anterior and po...
CIL:22756
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
axonemal dynein complex assembly
Cellular Component
axonemal dynein complex
A segment of the edge of the axoneme showing the outer axonemal dynein arms that extend from the A-subfiber of a doublet to bind to the B subfiber of the adjacent doublet. TEM taken on 4/21/88 by C. S...
