The mitochondrion is an organelle in most eukaryotes, though some cells and unicellular organisms may lack or alter them. Monocercomonoides uniquely lost its mitochondria. Derived from "mitos," meaning thread, and "chondrion," for granule or grain-like, these double-membrane-bound structures primarily generate cellular ATP, a key energy source.
