The two lipid bilayers around both mitochondria and chloroplasts are artifacts of the theory that they are both organelles that resulted from an original symbioses of a bluegreen alga (a type of photosynthetic bacterium) in the case of the chloroplast and a bacterium in the case of the mitochondrion. Both would have their own cell membrane and they were each separately taken in surrounded by a membrane of a host cell. Thus the two membranes.
