CIL:36617
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
cortical cytoskeleton organization
Cellular Component
cell cortex
Quick-freeze deep-etch of granulo-fibrillar material at the crests of the ridges. This material is composed of thinner and shorter filaments that, like the striated bands, appear to bind to the membra...

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...

Paramecium multimicronucleatum
Biological Process
peroxisome organization
Cellular Component
peroxisome
Peroxisomes are sometimes associated with lipid bodies as they are in this example. This cell was pretreated with 4% DMSO which increases the permeability of its membranes. Thus the peroxisomes are st...

Paramecium multimicronucleatum
Biological Process
pronuclear migration
Cellular Component
pronucleus
In an enlargement of a pronucleus in the chromatin material appears as sparsely scattered opaque bodies, as may be expected of a haploid nucleus, in a medium dense nucleoplasm. The nuclear envelope of...

Paramecium multimicronucleatum
Biological Process
organelle assembly
Cellular Component
trichocyst
In the case of a developing organelle, once the vesicles have grown to 1-2µm in diameter an electron-opaque crystal begins to grow at the center of the developing trichocyst. The paracrystalline mate...

Biological Process
digestive system process
Cellular Component
phagolysosome
A DV-III contains a thick continuous glycocalyx (polysaccharide coat) on the luminal side of its membrane as well as paracrystalline material, both provided by the fused lysosomes. The latex beads ind...

Paramecium multimicronucleatum
Biological Process
cortical cytoskeleton organization
Cellular Component
cell cortex
Striated bands in a transverse ridge (in which kinetodesmal fibers are lacking) at high magnification. The longer band has seven stripes rather than five as in the shorter band. This suggests three re...

Immunogold label specific for L1 antigen on DV-II. Monoclonal antibody to antigen L1 specifically labels DV-II and acidosomes but not lysosomes. Lysosomes are osmotically active so they tend to shrink...

Paramecium multimicronucleatum
Biological Process
plasma membrane organization
Cellular Component
plasma membrane
The plasma membrane of Paramecium multimicronucleatum seen in a freeze fracture replica. The two rows of IMPs can be seen on the P-face of the plasma membrane that connects the plasma membrane to the ...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
microtubule cytoskeleton organization
Cellular Component
cytoproct
High resolution image of a colchicine-treated cell, used in an attempt to disrupt its microtubules. We found that microtubules already formed are not disrupted in Paramecium multimicronucleatum. This ...
