Biological Process
cv diastole
Cellular Component
contractile vacuole
An image of the contractile vacuole in diastole (filling phase). Decorated spongiome surrounds the CV. The macronucleus, micronucleus, cytopharynx, and basal bodies of perioral membranelle are include...

macronucleus organization
Cellular Component
macronucleus
Transmission electron micrograph of section through the macronucleus of Nassula sp containing many darkly staining nucleoli.
CIL:15470
NCBI Organism Classification
Didinium nasutum
Biological Process
macronucleus organization
Cellular Component
macronucleus
Food vacuole and macronucleus of Didinium. The food vacuole contains unexploded trichocysts of Paramecium. Further details available at Wessenberg, H. and Antipa, G. 1968. Studies on Didinium nasutum....

NCBI Organism Classification
Tetrahymena pyriformis
Biological Process
macronucleus organization
Cellular Component
macronucleus
High resolution image of the nucleoli of the macronucleus. Nucleoli have a core of DNA that contains the genes that are transcribed into ribosomal RNA. Assembly of the ribosomal subunits from this pro...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
nuclear pore distribution
Cellular Component
macronucleus
Grazing thin section through the nuclear envelope of a macronucleus. Nuclear pores are packed so tightly that they often form a hexagonal array with 6 pores surrounding a central pore. The pores often...

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...

Halteria grandinella
Biological Process
macronuclear organization
Cellular Component
macronucleus
High resolution transmission electron micrograph of Halteria showing both the large macronucleus with nuclear pores, dense heterochromatin bodies and nucleolus, and the small micronucleus.
