CD3 mutant wheat (deficient in chlorophyll b) was germinated and grown for 6 days in the dark, greened at low light intensity for 4 days, then prepared for thin section electron microscopy. Under thes...

Confocal micrograph of a green alga, Penium margaritaceum. The cell wall is shown in green and the chloroplast is represented by autofluorescence. Honorable Mention, 2011 Olympus BioScapes Digital Ima...

Unicellular alga Penium, treated with the microtubule poison oryzalin. Fifth Prize, 2009 Olympus BioScapes Digital Imaging Competition®.

Cytoplasm of a green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this view the abundant endosymbiotic zoochlorellae and a single endosymbiotic bacteriu...

Cells of the unicellular photosynthetic alga Chlamydomonas reinhardtii were fixed, sectioned, and examined by transmission electron microscopy. In this section of the ac-5 mutant grown phototropically...

Isolated chloroplasts of the unicellular photosynthetic alga Chlamydomonas reinhardtii were cryofixed, freeze-fractured, and surface replicas observed by transmission electron microscopy. This close-u...

High magnification freeze-fracture image of a chloroplast from barley (Hordeum vulgare)showing the occasional repeating array of tetrameric particles. Other images in this group show the more typical ...

High magnification freeze-fracture image of a chloroplast from barley (Hordeum vulgare)mutant lacking chlorophyll b showing an example of the occasional repeating array of tetrameric particles. Other ...

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...
