Quick-freeze deep-etch rotary shadowed replica of a parasomal sac from which a clathrin-coated preendosomal vesicle has pinched off. The typical clathrin cage structure is preserved. Fractured trichoc...

In an enlargement of a pronucleus in the chromatin material appears as sparsely scattered opaque bodies, as may be expected of a haploid nucleus, in a medium dense nucleoplasm. The nuclear envelope of...

This micrograph through an oblique section of the cortex of Coleps shows many ribosomes ordered into whorls and spirals, collectively called polysomes, on the surface of the rough endoplasmic reticulu...

The pellicular pore consists of the invaginated plasma membrane that penetrates the alveolus as well as the epiplasm and ends as a clathrin-coated pit. TEM taken on 3/14/72 by R. Allen with Hitachi HU...

These Closterium algae are elongate desmids formed by two hemicells that are mirror images of each other. Although there is only a single central nucleus, each semicell has one or two axial, ridged c...

Scanning electron microscope image of longitudinal section of Oryza sativa (rice) stem. Image shows cuts through the vascular cells and cortex cells. Starch granules are visible inside the vascular ce...

Rendered 3D projection of a confocal z-series taken of rhizome (underground portion of the stem) of Convallari majalis (Lily of the Valley). The green objects represent reconstructed chloroplasts; ce...

Differential interference contrast micrograph of a Micrasterias, a type of green alga called a desmid. Each cell is constructed of two semicells which are mirror images of each other. The two semice...

A high resolution of a quick-freeze deep-etch rotary shadowed replica of a parasomal sac from which a clathrin-coated preendosomal vesicle has pinched off. The typical clathrin cage structure is prese...

Mitochondria of Vorticella convallaria like other ciliates, have tubular cristae arising from their inner membranes. However, they also have a bundle of filaments (DNA?) that extend through the center...
