The video explains the endosymbiotic theory, which suggests that mitochondria and chloroplasts were once independent prokaryotic cells that became integral parts of eukaryotic cells. It describes the evolution of eukaryotic cells from prokaryotes, highlighting the development of the endomembrane system and the formation of the first eukaryotic cell. The video details how mitochondria and chloroplasts originated through endosymbiosis, providing evidence such as their replication method and genetic similarities to prokaryotes. The video concludes with a call to action for viewers to engage with the content.
