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...

phagolysosome
The entire membrane of the phagolysosome does appear to have been changed into that similar to the lysosome membrane which bears a thick glycocalyx (polysaccharide coat) and no longer appears to be li...

food vacuole
A freeze-fracture image of a DV-II transforming into a DV-III by rapid fusion of lysosomes with its membrane. The P-face shown here of the early DV-III has abundant IMPs as well as many inward blebs (...

Biological Process
digestive system process
Cellular Component
phagolysosome
Following digestion, that only occurs in the phagolysosome (DV-III), the membrane of these DVs undergoes extensive tubulation. These tubules are ~45nm in diameter and arise from the cytosolic surface ...

digestive system process
Cellular Component
phagolysosome
The tubules arising from late DV-III expand at their distal ends into rounded shapes. These expanded ends contain a glycocalyx like the secondary lysosomes and large IMPs also like secondary lysosomes...
