plasma membrane
Freeze fracture of the plasma membrane and outer alveolar membrane of the pellicle of V. microstoma. The surface of Vorticella is encircled by rings which follow the septa of underlying alveoli. In th...

cytoskeleton
Purified rabbit skeletal muscle myosin in 0.6M KCl was deposited onto mica flakes, quick-frozen by contact with a liquid helium- cooled copper block in a Heuser-type cryopress, and freeze-etched in a ...

Cellular Component
secondary lysosome
Secondary lysosomes in quick-freeze deep-etch images lie against the smooth E-face of a phagoacidosome (DV-II) membrane. The P-fracture face of one fairly large lysosome lies close to the DV-II but no...

cell cortex
The infraciliary lattice in this quick-freeze deep-etched image consists of a meshwork of branching fibers composed of many subfibers. Basal bodies and trichocyst tips extend through the openings of t...

cytoplasm
The cytoplasm of P. multimicronucleatum like all other cells contains a large number of organelles that are membrane bound. Membranes are used to compartmentalize and isolate metabolic and enzymatic p...

early phagosome
The carrier vesicles dock with the acidosomes and then fuse with these larger vesicles before or as the vesicles dock at the nascent Digestive Vacuole. Thus the contents of the carrier vesicles are fi...
