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...

Isolated chloroplas tmembranes of the unicellular photosynthetic alga Chlamydomonas reinhardtii were fixed, sectioned, and examined by transmission electron microscopy. In this ac-5 mutant, regions of...

Isolated chloroplast membranes of the unicellular photosynthetic alga Chlamydomonas reinhardtii were cryofixed, freeze-fractured, and surface replicas observed by transmission electron microscopy. The...

Leaves from wildtype Arabidopsis thaliana were fixed, embedded, sectioned, reacted with antibodies to the FtsZ1-1 protein, a prokaryotic cell division protein that is a structural homolog of tubulin. ...

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...

Wheat seeds were germinated and grown for 6 days in the dark, greened at high light intensity for 4 days, thylakoids prepared, plunge-frozen, and freeze-fracture replicas obtained and examined by tran...

Isolated chloroplast membranes of the unicellular photosynthetic alga Chlamydomonas reinhardtii were cryofixed, freeze-fractured, and surface replicas observed by transmission electron microscopy. Wit...

The plastids of plants germinated in the dark are termed etioplasts and possess quasi-crystalline structures termed prolammelar bodies that contain the phospholipid materials and chlorophyll precursor...
