CIL:9256
NCBI Organism Classification
Coleps hirtus
Biological Process
ingestion
Cellular Component
oral apparatus
High resolution of the microtubular bundles that compose rods that outline the food vacuole-forming zone of Coleps. Eleven of these rods that surround the oral apparatus are obliquely sectioned in thi...
CIL:9923
NCBI Organism Classification
Opercularia [NCBITaxon:168247]
Biological Process
cortical cytoskeleton organization
Cellular Component
oral apparatus
The cytostome of Opercularia divides the peristome from the cytopharynx. The cytopharynx starts where the alveoli end in the oral region. TEM taken on 6/13/69 by R. Allen with Philips 300 operating at...
CIL:9929
NCBI Organism Classification
Didinium nasutum
Biological Process
organelle organization
Cellular Component
rough endoplasmic reticulum
A high resolution image of toxicysts in the cytoplasm of cross sectioned non-dividing Didinium. Toxicysts (extrusomes) are multilayered cylinders that are discharged from the cytopharynx region during...
CIL:10244
NCBI Organism Classification
Halteria grandinella
Biological Process
macronucleus organization
Cellular Component
macronucleus
This image of Halteria was fixed in cacodylate-buffered fixative and stained. The round, dark bodies, possibly pigment granules, were transparent in other preparations are electron-opaque following th...
CIL:10249
NCBI Organism Classification
Halteria grandinella
Biological Process
DNA replication checkpoint
Cellular Component
macronucleus
The DNA replication band in macronucleus of Halteria. Like hypotrichs the macronucleus of this oligotrich has a DNA replication band where DNA is synthesized. The nucleolus is evident. TEM taken on 3/...
CIL:10370
NCBI Organism Classification
Nassula
Biological Process
cytoskeleton organization
Cellular Component
cell cortex
Nassula sp. Transmission electron micrograph of rows of cross-sectioned basal bodies at the cell surface. TEM taken on 3/4/69 by R. Allen with Philips 300 operating at 60kV. Neg. 16,000X. Bar = 0.5µm...
CIL:12306
NCBI Organism Classification
Nassula
Biological Process
cytoplasm organization
Cellular Component
cytoplasm
Endoplasmic reticulum, mitochondria with their tubular cristae and a Golgi stack. Ribosomes are scattered in the cytosol. TEM taken on 3/13/69 by R. Allen with Philips 300 operating at 60kV. Neg. 20,5...
CIL:12336
NCBI Organism Classification
Euplotes sp.
Biological Process
oral/aboral axis specification
Cellular Component
oral apparatus
The anterior end of Euplotes tilts upward and contains triplet rows of cilia which are elements of the AZM. Ridges between the membranelles of the AZM contain mitochondria and electron transparent ves...
CIL:12604
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 ...
CIL:12611
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
cortical cytoskeleton organization
Cellular Component
cell cortex
A high resolution micrograph showing four parasomal sacs in longitudinal section each at the base of a surface depression. Trichocysts extend into each lateral ridge (lateral ridges do not have kineto...
