Fig. 26.11 Chloroplasts and upward mobility in the terrestrial photosynthetic way of life.
Choloroplasts are a category of photosynthetic organelles. They presumably originated as
cyanobacteria that had been ingested by a eukaryotic organism. Chloroplasts have a double
membrane and are endosymbionts that have seen part of their genome transferred to the host cell
genome. The chloroplasts are photosynthetic and provide fixed carbon for the cell. Chloroplasts are
