A high resolution image of a section through the cytopharynx of Coleps showing the corrugated lips containing lamellae surrounding the atrium of the buccal cavity. Rods composed of hexagonally packed ...

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

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...

Colorized scanning electron micrograph of a diatom frustule. Diatoms are unicellular organisms and a major group of algae. Diatoms are encased within a hard cell wall made from silica (glass) known as...

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...

Light micrograph of volvox. Volvox are a relatively large (approximately 500 µm) green algae. They consist of hollow spherical colonies with up to 15,000 cells embedded in their gelatinous walls. E...

Nomarski differential interference contrast image of Eudorina. Eudorina consist of either 16, 32 or 64 (mostly 32) cells embedded in a spherical mass of gelatinous material. Each cell contains a chlo...

Single computed x-y slice through tomographic volume of blue green algae exposed to low light conditions. Reconstruction shows the chloroplast and inner thylakoid membrane. Some electron dense struc...

Single computed x-y slice through a tomographic volume of the chloroplast of a blue green algae exposed to low light conditions. The quality of the reconstruction is not very good due to alignment di...

Computed slice through tomographic reconstruction of blue green algae grown under high light conditions. This image has been downsampled from the raw data image which can be accessed using the link p...
