Quick-freeze deep-etch image of a cytosolic region where trichocysts are developing. Vesicles, even small ones, contain contents that are compacting into paracrystalline form. These vesicles seem to h...

Color-enhanced scanning electron micrograph of the inside of a guinea pig inner ear showing the hearing organ, or cochlea. Running along the spiral structure are rows of sensory cells which respond to...

Scanning electron micrograph of a 6 day old human embryo beginning to implant into the lining of the uterus (endometrium). As implantation progresses, the inner cell mass begins to form into the bila...

Colorized scanning electron micrograph of keratinised squamous epithelial lining of the upper vagina. The boundaries between adjacent cells are visible as raised ridges. The cells closest to the surfa...

Colorized scanning electron micrograph of pollen on the anther of a hedge mustard (Sisymbrium officinale) flower. This plant is reputed to have various medicinal properties including its ability to tr...

Freeze-fracture image of a barley (Hordeum vulgare) chloroplast from a mutant lacking chlorophyll b illustrating the changes from wildtype in particle distribution on the four types of cleaved thyla...

High magnification freeze-fracture image of a barley (Hordeum vulgare) chloroplast from a mutant lacking chlorophyll b illustrating the changes from wildtype in particle distribution on the PFs and ...

This colorized scanning electron micrograph shows the structure of osteocyte cells in the cortex of a mouse tibia bone. Osteocytes are the cells that form new bone. Imbedding the bone in resin, which ...

Scanning electron micrograph of the the fruiting body of bread mould. As the mould grows, it propagates itself by forming spores that are released into the environment and grow into new mould colonies...

Isolated chloroplast membranes of the unicellular photosynthetic alga Chlamydomonas reinhardtii were cryofixed, freeze-fractured, and surface replicas observed by transmission electron microscopy. The...
