Detail of fractured early Digestion Vacuole-III membrane showing the many IMPs on the P-fracture faces of the lysosomal membranes that had just fused with the DV. The membrane will smooth out as the p...

In quick-freeze deep-etch micrographs it is not easy to distinguish peroxisomes from surrounding organelles. The organelle at the top of this micrograph may be a peroxisome based on its finely granula...

A freeze-fractured view of the nuclear envelope. The fracture in the middle of the figure exposes the cytosolic facing membrane. This can be distinguished by a fractured cytoplasmic organelle at the t...

In quick-freeze deep-etch preparations the plasma membrane can be seen to contain plaques or plates of intramembrane particles (IMPs) that are regularly aligned in rows with a center-to-center spacing...

Freeze fracture image of the surface ridges at the anterior end of the cell where kineties to the right and left sides come together at an angle at the anterior suture tip. In this area are numerous p...

In quick-freeze deep-etch preparations the plasma membrane can be seen to contain plaques or plates of intramembrane particles (IMPs) that are regularly aligned in rows with a center-to-center spacing...

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...

Quick-freeze deep-etch rotary-shadowed replica of a portion of the chemically-unfixed cytopharynx. The cytopharynx is continuous with the plasma membrane and is covered by only one membrane which is p...

Figure 326 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. Cells of sense organs detecting vibration are provided with stiff surface projections, the size of cilia but lackin...

A high resolution image of portion of an isolated cilium exposing two rows of outer dynein arms arising from subfiber A of each doublet. The heavy chains of the dynein complex are linked to the microt...
