NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
nucleolar fragmentation involved in replicative aging
Cellular Component
macronucleus
An extreme example of peeling of the surface of nucleoli in which long threads unravel from the nucleoli. TEM taken on 5/27/82 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 14,250X. Bar = 0.2...

macronucleus organization
Cellular Component
macronucleus
This figure shows the connection between the peristome and the food vacuole forming zone where the alveoli end. The cytostome is the opening that connects these two zones. TEM taken on 6/13/69 by R. ...

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...

Vorticella convallaria
Biological Process
macronucleus organization
Cellular Component
macronucleus
Only the macronucleus contains nucleoli which is the site of ribosomal RNA synthesis and ribosome subunit assembly. This EM also contains the distal end of the food vacuole forming cytopharynx which c...

Opercularia [NCBITaxon:168247]
Biological Process
macronucleus organization
Cellular Component
macronucleus
The peristome is covered on one side by the oral cilia and on the opposite by the ribbed wall. Lamellae from the ribbed wall extend into the nascent food vacuole forming region, the cytopharynx. This ...
