~convert energy

(Chloroplasts)
are found in unicellular organisms such as plants, and
(Mitochondria)
 is found in almost all cells. (Chloroplasts convert light energy into sugar using photosynthesis,) and the (mitochondria converts sugar into ATP using cellular respiration.)

Both the mitochondria and chloroplast convert energy, have its own DNA, and are enclosed by two membranes.
