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 ...

Scanning electron micrograph of the epidermal surface of lamprey larvae. A row of microvilli outline the polygonal borders between cells, while short microvilli cover the external surface in a reticu...

Electron micrograph showing fingerprint like ridges called microplicae on the surface of fish skin epidermis from the neon tetra. These ridges offer mechanical reinforcement against trauma and help ho...

A high resolution image of the cortex of Paramecium consists of a plasma membrane and alveolar sacs, with their inner and outer alveolar membranes that limit the area in which endocytosis can easily o...

This freeze fracture view of the pellicle of V. microstoma near the aboral end of the zooid shows the region where the width of each circumferential alveolus is narrower and thus the strings of fractu...

A high magnification view of the above septum in planar view and the septal pores that connect adjacent alveoli. The pores always lie next to the junction of the septum with the outer alveolar membran...

The early days of electron microscopy provided the first views of cell ultrastructure. This electron micrograph shows the plasma membranes of two closely apposed glial cells from the central nervous ...

This electron micrograph shows the E-fracture face (above) and P-fracture face (below) of the membrane of adjacent epithelial cells from the ciliary epithelium of the monkey eye. Intramembranous part...
