Mitochondria are large organelles containing DNA and surrounded by a double membrane. The inner membrane is highly convoluted, with deep folds called cristae. The membranes divide the mitochondrion into two compartments, the central matrix, and the intermembrane space.
Mitochondria and Chloroplast carry some genetic information necessary for their function. The ribosomes are equivalent to Prokaryotic 70S ribosomes, and nyclear DNA encodes some of the component that makes up these ribosomes. Also, Mitochondria and Chloroplast have double membrane that surrounds these organelle. No one knows for sure. One hypothesis is that a long, long time ago a cell endocytosed a prokaryotic cell and these two cells formed a symbiotic relationship. The inner cell (mitochondria and chloroplasts) was protected from the environment and the outer cell received energy.
