CIL:36260
NCBI Organism Classification
Vorticella convallaria
Biological Process
micronucleus organization
Cellular Component
micronucleus
Like other ciliates two types of nuclei are present. A germinative micronucleus and a RNA-producing macronucleus. Both have nuclear envelopes with pores and both have ribosomes attached to their outer...

NCBI Organism Classification
Vorticella convallaria
Biological Process
contractile system
Cellular Component
macronucleus
Vorticella convallaria has a contractile stalk that arises from the aboral pole of the cell. The myonemes from the body converge at this pole and pass into the stalk to form a large contractile bundle...

NCBI Organism Classification
damselfly
Biological Process
skeletal muscle contraction
Cellular Component
myofibril
The image shows the surface of the ribbon-like myofibrils, with some remnants of the SR attached mostly at the Z lines. The regular disposition of attached cross bridges is visible in many areas. Mo...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
food vacuole
Monoclonal antibody, E30-2-1, was raised to antigen D6 that specifically labels acidosomes and DV-II. There was no label on the nascent vacuole membrane or ciliary membranes. This cell had been incuba...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
food vacuole
At the same time that the acidosomes fuse with the phagosome, the DV-I membrane, that originated from the discoidal vesicles, is transformed into tubules that are removed from the phagosome. By this p...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
early phagosome
By 5-8 minutes the membrane of the DV uniformly labels with the mAb to the L1 antigen that is specific for acidosomes and phagoacidosome (DV-II) membrane. An unlabeled lysosome lies next to the DV-II....

NCBI Organism Classification
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...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
phagolysosome
As with acidosome fusion with the DV-I, lysosome fusion with the DV-II also seems to occur nearly all at once resulting in a phagolysosome (DV-III) with a highly irregular surface. However, unlike the...

NCBI Organism Classification
Paramecium caudatum
Biological Process
cortical cytoskeleton organization
Cellular Component
coated pit
Ciliates such as Paramecium have specialized sites for endocytosis and exocytosis. Most of their surface is not available for internalization of membrane because of the underlying alveolar sac system....
CIL:36767
NCBI Organism Classification
Paramecium caudatum
Biological Process
cortical cytoskeleton organization
Cellular Component
coated pit
Receptor mediated endocytosis is a process in which extracellular molecules are taken into the cell via coated vesicles that pinch from the plasma membrane. In Paramecium the resulting vesicles fuse w...
