Electron micrograph of a thin section through a portion of the chloroplast of the unicellular green alga Chlamydomonas. Free ribosomes are seen as dark particles within the chloroplast stroma. They ar...

Freeze-fracture image of a chloroplast from barley (Hordeum vulgare) illustrating the characteristic size and distribution of particles on the cleaved thylakoid membrane surfaces. Particle distributio...

Transmission EM of cotyledons of the double knockout oep16.1/16.4 of Arabidopsis thaliana grown in the dark. The characteristic quasi-crystalline prolamellar bodies seen in dark grown plastids appear...

Freeze-fracture image of a chloroplast from barley (Hordeum vulgare) illustrating the characteristic size and distribution of particles on the EFu and EFs thylakoid membrane faces. The inset gives a h...

High magnification freeze-fracture image of a chloroplast from barley (Hordeum vulgare) illustrating the characteristic size and distribution of particles on the EFs and PFs faces of cleaved thylakoid...

Transmission EM of cotyledons of wildtype Arabidopsis thaliana grown in the dark and exposed to light for 16 hr. The prolamellar bodies have been partially converted into chloroplasts. Other images in...

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...

Thin section of a wildtype chloroplast of Arabidopsis thaliana showing the characteristic distribution of thylakoids membranes in stacked grana (black arrow) and unstacked stromal regions (white arrow...

Thin section of a chloroplast of Arabidopsis thaliana lacking the FZL protein, a member of the dynamin superfamily of proteins. FZL is related to FZO, a protein that mediates fusion between mitochondr...
