Differential interference micrograph (Nomarski) of late binary fission in the desmid algae, Micrasterias rotata.

Gloeotrichia, a colonial cyanobacterium. Filaments arrange themselves in starlike colonies. Large numbers of colonies can collect in freshwater lakes, forming blooms. Sixth Prize, 2005 Olympus BioSc...

Light micrograph of a transverse section through wheat stem showing uredosori of wheat rust (Puccinia graminis). These sori appear as rust-coloured streaks on the wheat. The released uredospores will ...

A Nomarski differential interference microscopy image illustrating the frustule (silica cell wall) of a marine centric, Aulacodiscus formosus diatom (unicellular alga). Diatoms are photosynthesising a...

A Nomarski differential interference micrograph of a filament of Nostoc sp, a nitrogen-fixing cyanobacterium.

Photomicrograph of a triangular marine centric diatom (unicellular alga). Diatoms are photosynthesising algae that live in most aquatic environments, both fresh and salt water. They are non-motile and...

Photomicrograph of Chlamydia grown in culture. The sample was taken from rhesus monkey kidney cells and stained with giemsa. The cell nuclei appear red and the infective 'elementary bodies' of the Chl...

Prosthogonimus macrorchis, a flatworm poultry parasite, imaged with Rheinberg illumination. Honorable Mention, 2010 Olympus BioScapes Digital Imaging Competition®. Prosthogonimus macrorchis has a com...

This is a region of a (semithin) longitudinal section of onion root taken from the meristematic zone; this is the undifferentiated region of plant tissue from which new cells are formed. Therefore, it...

This image illustrates the frustule (silica cell wall) of a warm-water marine diatom, Podocystis spathulata. Diatoms are aquatic, single-celled algae which possess a hard shell. The shapes vary but al...
