Receptor mediated endocytosis is a process in which extracellular molecules are taken into the cell via coated vesicles that pinch from the plasma membrane. In Paramecium the resulting vesicles fuse w...

Detail of the junction between the ribbed wall and the right side of the cytopharynx area. The ribbed wall is covered by alveoli and the ribs are produced by small narrow ridges similar to the larger ...

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 ...

The cytoproct is the cell’s defecation site where spent digestive vacuoles fuse with the plasma membrane. In this cell the cytoproct is closed and forms a ridge along the posterior suture on the ven...

The left edge of the cytopharynx is bordered by a complex architecture designed to transport a pool of flattened vesicles to this edge where they will fuse with the cytopharyngeal membrane to expand t...
