Explanation:
According to the endosymbiotic theory the origin of mitochondrion is from the prokaryotic organism: primitive host cell (future eukaryotic cell) engulfed prokaryotic cell (endosymbiont) that provided the functions that evolved into mitochondria. Both of them had benefits: the endosymbiont gained protection and some essential nutrients from the host, while host had the energy and oxygen source from the endosymbiont.
So, the plasma membrane of the endosymbiotic prokaryotic cell became the membrane of the mitochondrion.
