See the below image for the Miitochondrion diagram. The mitochondrion ( / ˌmaɪtəˈkɒndrɪən /, plural mitochondria) is a double membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells ).

Mitochondria are small membrane-bound organelles that are usually about 1 – 10 microns in length. They can be spherical or rod-shaped. The mitochondrion is enclosed by two membranes that separate it from the cytosol and the rest of the cell components.
