NCBI Organism Classification
Vorticella convallaria
Biological Process
digestive system process
Cellular Component
cell
11 micrographs of views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 4 food vacuoles. The helically contracted stalk is se...

NCBI Organism Classification
Vorticella convallaria
Biological Process
cortical cytoskeleton organization
Cellular Component
pellicle
Like other peritrichs the pellicle of Vorticella convallaria is sculpted into ridges and grooves that circle the cell perpendicular to the aboral/adoral axis of the cell body. Pellicular pores penetra...

Vorticella convallaria
Biological Process
cortical cytoskeleton organization
Cellular Component
cell cortex
V. convallaria preserved in collidine buffered fixative (not cacodylate) has a less dense cytoplasm in which oranelles are easier to recognize. The rough ER has vesiculated but this vesiculation enhan...

NCBI Organism Classification
Vorticella convallaria
Biological Process
contractile vacuole organization
Cellular Component
contractile vacuole
The contractile vacuole of V. convallaria empties into a convoluted chamber. This chamber is covered by the alveoli and plasma membrane of the pellicle and is open to the cell’s surface via the peri...

Cellular Component
oral apparatus
The buccal cavity opens into the developing digestive (food) vacuole at the terminal edges of the alveolar sacs that cover the buccal cavity. A plane connecting these edges would roughly describe a te...

Paramecium caudatum
Biological Process
phagocytosis
Cellular Component
pre-autophagosomal structure
One segment of the assembly line used for phagosome membrane growth in P. caudatum. Cytopharyngeal ribbons bring discoidal vesicles to the left lip of the cytopharynx where the vesicles bind and then ...
