Is the Mitochondria Always the Powerhouse of the Cell?

The video explores the fascinating world of microcosmos, focusing on how organisms obtain energy. It delves into the role of mitochondria as the powerhouse of the cell, tracing its origins and significance. The discussion extends to diplomonads, unique eukaryotes lacking mitochondria, and their evolutionary journey. The video challenges traditional views on eukaryotic evolution, highlighting the adaptability of life in anaerobic conditions and the presence of mitochondria-like organelles. It concludes by emphasizing the complexity and diversity of life forms and their evolutionary paths.
