Chloroplasts in situ are surrounded by jackets of a material which does not contain chlorophyll. The chlorophyll-bearing inner structure lacks motion while the jackets constantly change shape. Long protuberances may extend from the jackets into the cytoplasm and may segment into particles that cannot be distinguished from mitochondria. Segmentation and other dynamic characteristics of living plant cells have been recorded on cine film.
