(B) to (D) Division conformations of epidermal cell chloroplasts stained with silver nitrate from young expanding cotyledons. (E) Typical chloroplast in early division, from an expanding leaf mesophyll cell. (F) Confocal topographic view of dumbbell-shaped plastids in the base of petals in the Arabidopsis arc5 mutant. (G) A mature Arabidopsis mesophyll cell showing part of the monolayer of chloroplasts over the internal cell surface with a large hole in the monolayer representing where the cell was previously attached to a neighboring cell. (H) An electron micrograph of arc5 petal chloroplasts showing an electron-dense plastid dividing ring at the narrow isthmus of a chloroplast in division (photograph courtesy of K. Hagley).
