Fluorescence microscopy image of a spherical cluster of chloroplasts, showing magenta-stained interiors surrounded by bright green outlines against a black background.

Moss (Physcomitrium patens) protoplasts (wallless cells) transformed with chloroplast envelope protein tagged with mGFP (green). The chlorophyll autofluorescence is in magenta.
The protrusions of the chloroplast envelope are called stromules.
