The P-face of the plasma membrane of a semicell engaged in the synthesis of the secondary wall. Hexagonal arrays of rosettes of varying size and shape can be observed. Propanejet freezing. Technical d...

This is one of six images in Figure 6 in Apaja et al., JCB 2010 that shows the fate of various model membrane proteins, that are either folded or in the unfolded state at the plasma membrane, expresse...

The contractile vacuole pore is supported on its cytosolic side by a coil of microtubules and other microtubules extend from the pore to the CV membrane. The plasma membrane and CV membrane cover the ...

Septa of bordering alveoli when lying in the plane of section exhibit pores at their outer margins closest to the plasma membrane. This shows that there is physical continuity between the lumens of al...

Ema localizes to endosomes. Third instar larval garland cells expressing Ema-GFP fusion protein and stained for the late endosomal and lysosomal protein Spinster (red) and plasma membrane and nuclei (...

Ema localizes to endosomes. Third instar larval garland cells expressing Ema-GFP fusion protein and stained for the early endosomal protein Rab5 (red) and plasma membrane and nuclei (blue). Ema does n...

Vorticella convallaria has a contractile stalk that arises from the aboral pole of the cell. The myonemes from the body converge at this pole and pass into the stalk to form a large contractile bundle...

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...
