Meanings
-
A membrane-bound form of organelles that produce molecular hydrogen and ATP in some anerobic ciliates, trichomonads and fungi, remarkable in that most forms contain no DNA.
Hydrogenosomes, like almost all other organelles, always grow by proliferation of preexisting organelles. Thus, each daughter cell will receive a complete set of organelles during cell division. Morphological evidence was presented showing that trichomonad hydrogenosomes, like mitochondria, may divide by three distinct processes: (1) segmentation, (2) heart-form division, and (3) partition. In the segmentation process, the hydrogenosome grows, becoming elongated with the appearance of a constriction in the central portion[…]
