Section through the cytopharynx of Coleps showing the corrugated lips containing lamellae surrounding the atrium of the buccal cavity. Rods composed of hexagonally packed microtubules that support the...

Colorized scanning electron micrograph of a biofilm on carbon steel after immersion in sea water for 14 days. A biofilm is an aggregate of microorganisms that adhere to each other on a surface and ar...

This scanning electron micrograph shows mycroplasma (colorized pink), a genus of bacteria that lack a cell wall. Without a cell wall they are unaffected by many common antibiotics, such as penicillin,...

Colorized scanning electron micrograph of a human embryonic stem cell (gold) growing on a layer of supporting cells (fibroblasts). Stem cells are derived from very early embryos and can either be grow...
