An electron micrograph of a potion of a cell of the unicellular alga Chlamydomonas reinhardii illustrating the eye spot, an organelle found inside the chloroplast that is composed of red carotenoid pi...

Brightfield micrograph of a living diatom (Mediopyxis helysia) showing the cell nuclei and golden chloroplasts. There is a bacteria colony in mucilage located on the top of the diatom. The image won ...

The single chloroplast of the unicellular alga Chlamydomonas reinhardtii contains an orange carotenoid pigment spot that functions in phototaxis. The 'eyespot' is seen in this 250 nm epon section imag...

An electron micrograph showing a central longitudinal section of the unicellular green alga Chlamydomonas reinhardtii (y-1 yellow mutant) grown in the light. The single cup shaped chloroplast with p...

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...

Computed slice through a tomographic volume of a chloroplast from Phaeocystis antartica, a blue green algae, grown under low light conditions. This image has been downsampled from the raw data image...

Single tilt image taken at zero degrees tilt of a 0.75 um section of blue green algae imaged using intermediate voltage electron microscopy. Contrast is reversed so that electron dense structures app...
