Even if the well-known endosymbiotic theory is right, and once free-living single-celled organisms evolved to become organelles within larger cells, much remains unexplained about how, exactly, ...

Intracellular endosymbionts that originally descended from free-living prokaryotes have been important in the evolution of eukaryotes by giving rise to two cytoplasmic organelles. Mitochondria arose ...

Mitochondria and chloroplasts are essential eukaryotic organelles of endosymbiotic origin. Dynamic cellular machineries divide these organelles. The mechanisms by which mitochondria and chloroplasts ...

Ostracods, sometimes called seed shrimp, are nearly microscopic, aquatic organisms, inhabiting all types of marine and ...
