Formation of mitochondria in Boderia (Protozoa: Foraminiferida)

Summary Approximately 25 per cent of the mitochondria in one day old, rapidly growing, schizonts of Boderia vary considerably in their morphology from the consistently spherical organelles present in adult animals. Mitochondrial biogenesis by division is indicated and illustrated. The internal reorganisation of the mitochondrion which occurs prior to fission has not been reported previously for this organelle.
