There _is_ a hypothesis that chloroplasts evolved as endosymbionts and
retain vestiges of genetic autonomy but the close integration of their
photosynthetic role with the rest of the cell's metabolic activities in
differentiated, photosynthetically active cells makes it difficult to
believe that chloroplasts develop independantly of the cells containing
them.

Can you elaborate on the recent observations that you have made?
