Tetrahymena pyriformis
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The bottom of the buccal cavity is surrounded by specialized cytoplasm and contains a lip that constricts the opening leading through the cytostome into the receiving vacuole or nascent vacuole. The ...

phagocytosis, engulfment
Cellular Component
phagocytic vesicle
The nascent digestive vacuole forms as the membrane of flattened vesicles fuse with the single membrane of the cytopharynx between the lamellae (2 microtubules forming a lamella) that are connected al...

contractile vacuole organization
Cellular Component
contractile vacuole
The contractile vacuole pore is coated on its cytosolic side by helically wound microtubules. Other microtubules abut this helix and extend out to the surface of the contractile vacuole where they are...

macronucleus organization
Cellular Component
macronucleus
An 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 processed RNA an...
