Expert Answer:

Mitochondria is a cellular organelle found in large numbers in all eukaryotic cells. It is the site of respiration (ATP synthesis) and contains its own DNA. It has a double membrane, the inner layer being folded inward to form layers (cristae).
Chloroplast is a plastid (a cellular organelle) that contains chlorophyll and in which photosynthesis takes place. Chloroplasts are present in plants and some protists, converting solar energy to chemical energy in sugars. This plastid gives the green colour to leaves and stems.
